Verisign is an Internet infrastructure service provider. It is based in Reston, VA and was founded in 1995. The company has offices around the world, in Virginia, California, Washington D.C., India, Brazil, China, Australia, Switzerland, and the UK.

Its registry services include operating the authoritative directory for the following TLDs:

Verisign runs two of the world's thirteen root servers: and, which are considered national IT assets by the U.S. Federal government. During the fourth quarter of 2015, Verisign’s average daily Domain Name System (DNS) query load was approximately 123 billion queries per day across all TLDs operated by Verisign, with a peak of nearly 194 billion; this represents a daily average increase of 2.8 percent, while the peak decreased 67 percent.[1]

Verisign was also well-known for its authentication services, which included business authentication services such as implementing and operating secure networks, utilizing SSL protocol, encrypting transactions and communications, and user authentication services such as identity protection, fraud detection, and public key infrastructure.[2] Those services were sold to Symantec in 2010.[3] Prior to selling those services, Verisign had 3,000,000 certificates in operation, which made it the largest Certificate Authority behind the encryption and authentication on the Internet.[4]

In September 2015, Verisign's registry management for .com domains passed the 118 million mark.[5] In the first quarter of 2012, figures showed that it held more than 50% of registrations for all TLDs.[6] By the end of 2012's second quarter, Verisign had 240 million domain names across all of the TLDs it operates, with .com and .net holding 49% of the TLD market share, a drop of 2% from the first quarter.[7]

Products and Services

Verisign provides its services through two divisions, its Internet Services division and the Security Service Division. The Internet Services division includes Naming & Directory Services such as domain name registration for .com and .net, and DNS-related and RFID services.

In January 2012, Verisign raised the wholesale prices of .com and .net registration by 7%, increasing the price from $7.34 to $7.85. Registrars generally passed the price increase on to their customers. Some used it to raise their own prices beyond the 7% increase, by increasing prices by 10 to 12 percent.[8]

In its 2012 10-K report, Verisign identified ARI Registry Services, Neustar, Afilias, and Nominet as its primary competitors.[9]

The following three services -- Managed DNS, DDoS Protection, and iDefense -- are individual services, but are available together as a part of Verisign's "Uptime Bundle", designed with four different pricing and service packages to meet the needs of a variety of organizations.[10]

Managed DNS

Verisign's in-house DNS services are comprised of a globally deployed constellation of sites offering cloud-based hosting solutions which enable organizations with critical online systems to confidently move support for DNS resolution outside of their internal teams. Given Verisign's expertise and scale, their services reliably optimize availability and performance at what would be a fraction of the combined costs for system administrator time, patching, hardware purchase, deployment, maintenance, and bandwidth required to support DNS management internally. Using a secure Web-based portal, Verisign Managed DNS customers maintain secure, exclusive, and direct control over their DNS data, which includes IP address, MX records, SOA values, aliases, PTR records, NS records, and text records. The portal also provides real-time record propagation, record-level control of time-to-live (TTL) settings, and zone file error-checking to reduce DNS outages from human error.[11]

Verisign first launched managed DNS programs in 2003; however, in August 2010, its services were relaunched with a focus on large organizations that depend on optimized and reliable DNS. When announcing their DNS service launch, it was noted that the company's experience managing the large .com, .net, and other root zone files make it a clear competitor in what was, at the time, a relatively small group of DNS service providers. Their DNS services are part of the larger package of iDefense and DDoS protection services.

Verisign is able to claim fast response times given its globally deployed DNS servers, reliable content delivery networks, and directive location services. This is part of its Global Load Server Balancing (GLSB), which also enables automatic fail-over, which means that in the event that a server goes down, affected clients will then be redirected to an alternative server. Other features include split DNS for the maintenance of separate namespaces for internal and external clients.[12]

Since March 2011, Verisign's DNS services include full support for DNS Security Extensions (DNSSEC) compliance features and Geo-Location capabilities. It facilitates the process of managing DNSSEC by signing all zone files in a customer's account, continually checking the status of DNSSEC keys to ensure they are valid, and automatically publishing new keys after the existing ones expire, which is considered the most challenging component of DNSSEC. The Geo-Location capabilities allow customers to differentiate responses to DNS queries and optimize network performance, which in turn allows Verisign's customers to deliver location-specific content, offers, and advertisements more relevant to potential customers.[13]

In order to maintain a position as a top-level Internet domain, Verisign's DNS network has to have a capacity of 100 times the peak load it sees in a year.[14]

DDoS Protection Services

Verisign's expertise with large-scale network infrastructure once again comes into play with regards to its DDoS Protection Services, which use proprietary filtering technology to stop distributed denial of service (DDoS) attacks in the cloud before they ever reach a customer’s network. The services are network and hardware agnostic, require no hardware installation, and are able to detect and filter malicious traffic away from enterprise websites.[15]

Verisign's DDoS Protection Services began as an offering for large financial institutions, but in May 2011, as the frequency of DDoS attacks on the Internet increased, Verisign began to also offer these same cloud-based services at small and midsize businesses as well. In addition to these proactive services, it also began offering reactive services that allow businesses, particularly small businesses, to call Verisign after an attack.[16]

The need for and attention on these services increased after the 2009 holiday shopping season, when major attacks took down the sites of e-retailers such as Walmart, Amazon, Expedia, and Gap.[14]

iDefense Security Intelligence Services

Verisign iDefense Security Intelligence Services give customers access to current and actionable intelligence related to vulnerabilities, malicious code, and global threats. Verisign has an experienced multinational network of security experts acting as an extension of their customers' teams, giving them exclusive access to the most in-depth cyber threat intelligence available. This includes intelligence to avoid false alarms.[17]

In February 2010, Agiliance Inc., a leading independent provider of Integrated Governance, Risk and Compliance (GRC) solutions, announced that its threat and vulnerability automation solution would be integrated with iDefense Security Intelligence Services.[18]

In 2012, Frost and Sullivan recognized Verisign's iDefense with the 2012 North American Frost & Sullivan Award for Product Differentiation; the decision was made based on its analysis of the vulnerability research market. Frost & Sullivan Research Analyst, Richard Martinez, noted that "Verisign iDefense Security Intelligence Services provide around-the-clock access to relevant and actionable cyber intelligence, supporting decision-makers with threat awareness, vulnerability management, and incident management resources." It was also noted that Verisign created the iDefense Vulnerability Contributor Program with hundreds of expert vulnerability researchers from around the globe, to provide insight into the cyber underground, undiscovered vulnerabilities, and global threats in more than 20 languages.[19]

Relationship with ICANN

Verisign existed before ICANN, and thus with the establishment of the Internet's oversight body, Verisign was in a place of sustained recognition as the registry of many of the Internet's most important TLDs. While it has given up some of its original TLD oversight, it continues to manage the Internet's most well-known extension, .com, and others.


Verisign is consistently one of the largest sponsors of ICANN's meetings; they sponsored at the Platinum level or above for all 2011 meetings.[20][21][22] Some commentators attributed the ability of ICANN to secure former U.S. President, Bill Clinton, to speak at ICANN 40 with the especially high level at which Verisign sponsored that meeting.[23][24]

Site Finder Service

Verisign launched its Site Finder service in September 2003, which redirected end-users to its Site Finder search engine if they attempted to access unregistered web addresses. ICANN published a report against this policy stating, "Verisign violated architectural principles, codes of conduct and good practice," and ICANN declared Site Finder in violation of Verisign's contracts for running the master address lists for .com[25] ICANN then asked Verisign to suspend its Site Finder service.[26] In October, a hearing took place in Washington, D.C. to review technical issues with the U.S. Department of Commerce, which authorizes Verisign to operate the DNS for .com and .net. VeriSign subsequently shut down the service.

In February 2004, Verisign sued ICANN claiming Verisign had unlawfully been prevented from adding new features to .com and .net.[27]. In August 2004, the claim was moved from federal to California state court.[28] More than a year later, in late 2005, Verisign and ICANN announced a proposed settlement that introduced new terms for registry services in the .com registry. The documents of these agreements are publicly available at ICANN's official website and can be viewed here.

.com Renewals

The dropping of the aforementioned litigation between Verisign and ICANN cleared the way for the renewal of the .com registry agreement from 2005 through 2012.[29] The agreement and its appendices can be viewed via the ICANN site here.

In March 2012, ICANN posted a proposal for Verisign's potential renewal of the 2006 .com registry agreement.[30] Three months later, in June 2012, the ICANN Board went against community suggestions to approve Verisign's .com registry agreement for an additional seven years after its expiration on November 30th, 2012. According to the ICANN decision, Verisign would've also been allowed to increase its registry fee by 7% in four out of the next seven years,[31] but this decision was changed by the Department of Commerce. Nonetheless, the new policy will result in Verisign paying ICANN a $0.25 fee for every .com registration, renewal, or transfer, instead of the lump sums it paid previously, potentially netting ICANN an additional $8 million in revenue annually.[32][33] The original board resolutions can be viewed here.

In August 2012, three of ICANN's Constituencies (ALAC, GNSO Business Constituency, GNSO Intellectual Property Constituency) sent a letter to ICANN complaining that the organization held its renewal talks with Verisign behind closed doors and the result is that there are no Thick Whois requirements for the .com TLD.[34] The decision could not move forward without approval from the Department of Commerce, which Verisign received on November 29th, 2012.[33][35]

Verisign is to serve as the registry operator for .com from December 2012 through November 2018, with new terms and conditions, including:

  • Verisign's current pricing of $7.85 per domain name registration will remain unchanged for the next six years;
  • Verisign no longer holds the right to increase prices up to seven percent over the six-year term, and all-new price increases will be circumstantial and subject to Commerce Department approval.[35]

Those who benefit most from the prize freeze include consumers, those who purchase .com domain names in bulk, brand owners who maintain expensive defensive registrations, and registrars who no longer need to pass on cost increases to their consumers.[36]

"Consumers will benefit from Verisign's removal of the automatic price increases," said Larry Strickling of NTIA. "At the same time, the agreement protects the security and stability of the Internet by allowing Verisign to take cost-based price increases where justified."[37]

If ICANN's New gTLD Program becomes successful and "market power" is removed from .com's, Verisign believes that all price caps on .com's could be lifted as early as 2014.[38]

.net Renewals

In other domain name negotiations with ICANN, Verisign traded the .org TLD in return for continued rights over .com. In mid-2005, when Verisign's contract for the operation of the .net TLD expired, Verisign and five other companies bid for it. Verisign was supported by renowned IT companies like Microsoft, IBM, Sun Microsystems, and MCI. On June 8, 2005, ICANN announced that Verisign had been approved to operate .net until 2011.[39] These agreements have the presumptive right of renewal clauses that encourage the registry operators to invest in critical Internet infrastructure. Verisign was subsequently approved to operate the .net registry through 2017.[40]

.net Audit

In January 2013, Senior Vice President Pat Kane sent ICANN a letter stating that it had no intentions of submitting to an ICANN audit of its .net registry. Kane wrote, "Verisign has no contractual obligations under its .net Registry Agreement with ICANN to comply with the proposed audit. Absent such express contractual obligations, Verisign will not submit itself to an audit by or at the direction of ICANN of its books and records." This comes directly after implementing a new "Contractual Compliance Audit Program", introduced under new CEO Fadi Chehadé in mid-late 2012 as a 3-year plan to ensure all registries and registrars are following their contracts. A registry audit would entail a review of compliance with Whois, zone file access, data escrow, monthly reporting, and other policies outlined in the registry agreements. Mr. Chehadé had made a big focus of Contract Compliance and had promoted the head of Compliance, Maguy Serad, to report directly to him.[41]

New gTLDs

IDN Transliterations of .com & .net

In December 2011, weeks before the opening of ICANN's new gTLD program, the Chinese national registry, CNNIC, announced that it was applying for the IDN equivalents of .company, and .network.[42] This move was seen as potentially problematic given Verisign's own plans to seek the IDN equivalents of their .com and .net TLDs, such as their intention to apply for multiple transliterated versions of .com and .net.[43] Verisign's Pat Kane later added in January 2012 that the company was planning on applying for "about 12" new gTLDs, and noted that most of these were going to be foreign language transliterations of .com.[44] Expected languages included Japanese, Korean, Chinese, Cyrillic, Arabic, and Hebrew.[45] It was also noted then that Verisign had already been chosen to provide registry services for several .brand initiatives.[46]

During its first-quarter earnings report, on April 26, 2012, it was confirmed that Verisign would be applying for 14 new gTLDs, 12 of which are foreign language transliterations of .com and .net.

The languages chosen for transliterations include: Thai, Deva, Korean (Hang), Chinese (Hant/Traditional & Hans/Simplified), Hebrew, Russian, Arabic, Japanese. The two non-IDN applications by the company are for .comsec and .verisign.

In July 2013, Verisign's Pat Kane outlined in an article[47] the company's plans for allowing existing registrants of second-level IDN domain names to secure the matching domain under Verisign's new IDN gTLDs. For example, if you're the registrant of the Hebrew word for "website" that is registered as a second-level domain under .com, you will have the rights to that second-level name under the gTLD "קוֹם." but you will not have the rights under the Hebrew transliteration of ".net" if it existed.[48]


They also announced that they had been contracted by 220 new gTLD applicants to provide technical backend services.[49][50] They were the fourth most popular registry services provider, contracted by a total of 12% of applicants.[51]


In November 2012, the three entities most responsible for the Internet's Root Zone, ICANN, NTIA, and Verisign, confirmed that they were prepared with enough resources to launch up to 100 new gTLDs per week.[52]

Trademark Clearinghouse Model

In October 2012, a coalition of the world's most prominent registries, Neustar, ARI Registry Services, Verisign, and Demand Media jointly proposed two models for the mandatory new gTLD Sunrise period and Trademark Claims service involved in the Trademark Clearinghouse that differ from ICANN's. To excerpt their letter:

"This proposed model simplifies the ICANN model by decreasing the coupling between the Trademark Clearinghouse (TMCH) and registries. The model is as follows:

  1. The TMCH generates and maintains a global public-private key pair and provides the public key to the registrars and registries. This can be done simply by publishing the public key on the TMCH website. This website should be provided over HTTPs using a digital certificate from a reputable certificate authority. The DNS records associated with this website should be protected using DNSSEC. We believe that there are no issues with the security of the public key and anyone in the world can have access to it.
  2. Once the TMCH has authenticated the trademark information provided by the trademark holder and validated the use requirements for eligibility to participate in sunrise, the TMCH signs the sunrise (trademark) data with its private key. The digitally signed information is referred to as the ‘Signed Mark Data’ (SMD) and is provided to the mark holder. Typically, this would be in the form of a file download from the TMCH website. The SMD includes all of the domain labels (domain names) possible to be used in registrations for the validated trademark (IDN variants excluded).
  3. As each TLD begins its sunrise phase, the mark holder selects a registrar and provides the registrar with the SMD as part of an application for a name within the applicable sunrise period. The registrar (or its reseller) has the ability, if it chooses to, to validate the information using the TMCH public key and then forward the information to the registry to create the application.
  4. The registry verifies the signature of the SMD with the public key and verifies that one of the labels within the SMD matches the domain label being registered. The registry may also then verify any other information in the SMD to ensure it is consistent with the registry’s sunrise eligibility policies. The application, or domain name, is then created.
  5. At the closure of the sunrise round, the registry operator will then make allocations of domain names.
  6. The registry notifies the TMCH of the registered domain names for the purpose of notifying mark holders about the fact that a name was registered that matches their mark as well as reporting purposes. These notices will be referred to as ‘Notification of Registered Name’ notices (NORN). We believe that a daily upload of registered names to the TMCH is sufficient for the purpose of generating NORN notices.

This solution also works for those that are conducting 'first come – first served' style sunrise processes."[53]

Raises Questions on Security & Readiness

In late March 2013, Verisign sent ICANN and the U.S. Dept. of Commerce a report analyzing the readiness of ICANN to safely implement its New gTLD Program. The 21-page document covered a large variety of issues but focused on readiness and potential weak points in the program and the implementation of New gTLDs. Many speculated at reasons beyond public welfare for the report being issued, such as an interest in delaying the program due to its vested interest in the .com market dominance. Still, Verisign has over 200 new gTLD clients that are looking towards implementation in order to start profiting from or otherwise utilizing their applied-for extensions. ICANN's CEO, Mr. Fadi Chehadé, defended the organization's readiness and noted that the report contained no new information or areas that have not been addressed, stressing that the program was continuing on schedule with acute attention to all matters of security.[54]

Security Breach

As per routine for public companies, Verisign filed a quarterly 10-Q with the SEC in October 2011. The form contains a section for security issues that could compromise the company, in which Verisign disclosed a 2010 hack that affected limited parts of their computers and servers. While the disclosure suddenly got a lot of attention months later, one commentator argued that it was merely a "minor network breach".[55] Verisign has since reaffirmed that the DNS was not compromised.[56]

Selling Authentication Services Business to Symantec

Verisign's previous logo, a checkmark and the tag "VeriSign Secured", is one of the most trusted marks of secured websites. Even though providing Internet security was an initial objective of the company, Verisign shifted its priority over time to website management and its domain registration business.

Verisign began by selling some of its services piecemeal. Finally, in May 2010, Verisign sold the entire division to Symantec for 1.28 million.[3] Because of this deal, Symantec now has the right to VeriSign's authentication logo and the "VeriSign Secured" tag for SSL certification. Verisign's Security Services included managing services such as firewalls, intrusion detection and prevention, vulnerability protection, etc. It also provided global security consulting, email security, authentication and digital certificate/SSL validation, and Extended Validation (High Assurance) SSL Certificates.

BulkRegister Accusations

In May 2002, BulkRegister sued Verisign for Domain Slamming.[57] BulkRegister claimed Verisign "engaged in unfair practices" with a recent marketing campaign that attempted to get domain owners to use Verisign to renew their existing policy. In 2003, Verisign was found not to have broken the law and as a result, did not need to pay any fines. However, Verisign was barred from suggesting domain renewal or expiration prospects.[58]

Waiting List Service (WLS)

On December 30, 2001, Verisign proposed the implementation of the Waiting List Service (WLS) to ICANN's DNSO. Based on its proposal, the WLS will provide registrants with the opportunity to reserve preferred domain names that are currently registered by other subscribers. Registrars will directly reserve and transact with Verisign to reserve the domain name under the WLS. A domain name will only be transferred to an individual who made the reservation if the original owner submitted a request to delete the domain name. Verisign proposed a $35 fee for the service.[59]

Verisign revised its WLS proposals twice in response to public comments and discussions with registrars and other organizations, on January 28, 2002, and March 20, 2002, respectively.[60] [61] Despite objections, on August 23, 2002, ICANN approved the renegotiation of Verisign's .com and .net registry agreement to incorporate the proper amendments for the implementation of the WLS for 12-month trial periods. The final subscription fee was $24.[62]

On January 26, 2004, ICANN General Counsel and Secretary John Jeffrey sent Verisign the Conclusion of the Negotiation regarding ICANN's conditions prior to the implementation of the WLS wherein a special provision stated that the amendments made to the .com and .net registry needed approval from U.S. Department of Commerce (DOC).[63] The implementation of the WLS was delayed due to Verisign's failure to seek approval from the DOC and to make necessary changes to its .net registry agreement.[64]

Verisign filed a legal case against ICANN on February 26, 2004. The company accused ICANN of seriously abusing its technical coordination function by requiring Verisign to stop its Site Finder Service to the .com and .net domain namespace. The company also noted the delay of the implementation of the WLS and the inclusion of new procedures not required by the 2001 .com and .net registry agreements, such as the price reduction for the WLS service. According to Verisign, the conditions benefited the different ICANN constituencies but were unfavorable to the company. Furthermore, Verisign pointed out that ICANN denied the company the ability to profit by delaying the WLS while other companies were able to offer similar services to Internet users.[65]

United States District Court Judge Howard Matz dismissed the lawsuit on August 26, 2004. According to the judge, Verisign failed to provide sufficient evidence to prove its antitrust complaint against ICANN.[66] Verisign elevated the case to the Superior Court of California in Los Angeles,[67] and the two parties settled the lawsuit on February 28, 2006. The settlement permanently killed the WLS.[68]

Infrastructure Research Grant Program

The Infrastructure Research Program was launched by Verisign in 2010 as part of the 25th-anniversary celebration of the .com TLD. The company awarded a total of $300,000 to four compelling infrastructure research projects. Each project was given $75,000 and the program concluded in October 2011. In January 2012, the company announced that it will award two new $200,000 infrastructure research grants to compelling projects concentrating on topics of internet access and global infrastructural challenges, particularly those in developing countries. Experts in technology and policy development who have made significant contributions to the growth of the internet industry will judge the research project proposals.[69]
