Verizon Cybertrust’s Longtime Global Security Services Leader, Bryan Sartin, Joins eSentire as Chief Services Officer

Verizon Cybertrust’s Longtime Global Security Services Leader, Bryan Sartin, Joins eSentire as Chief Services Officer

eSentire, the world’s largest global Managed Detection and Response (MDR) provider, today announced that Bryan Sartin, longtime Global Security Services Leader for Verizon Cybertrust, has joined eSentire as Chief Services Officer. Sartin and his team will build upon eSentire’s award-winning MDR services and their Rapid Assist incident response (IR) solutions. Sartin is expanding the company’s cyber investigations, digital forensics, and incident response capabilities whereby eSentire can now provide partners and prospects with end-to-end IR services including breach remediation consulting. “As the extent and severity of the SolarWinds’ supply chain breach continues to unfold, it shows how comprehensive and damaging a cyber intrusion can be,” said Kerry Bailey, eSentire CEO. “For some time, our partners and prospects have been asking us if, in addition to providing our remote response capabilities, can we also provide ‘boots on the ground’ cyber investigations, forensics, and remediation services. Today’s organizations are smart, and they have a lot of security awareness. They know if a threat actor(s) wants to compromise their IT environment there are numerous ways bad actors can do it, all while circumventing the very best cybersecurity products and traditional services one might have in place,” continued Bailey. “Our partners and prospects have asked us to expand our IR services, so we have brought in one of the world’s top incident response experts to establish and lead what will be the security industry’s most capable forensics and incident response team,” said Bailey. “Our Rapid Assist partners already have a significant edge over the competition because of their access to Atlas, our award-winning Extended Detection and Response (XDR) cloud platform and our unique network sensor technology,” said Bryan Sartin, eSentire Chief Services Officer. “These assets will power a step-change in cutting-edge IR practices. For example, source identification, containment, and quantifying the magnitude of a compromise will now happen in tighter, more reliable timeframes than conventional approaches currently permit. The door is also open to improved customer experience and significantly shorter SLAs with respect to onsite intervention and threat suppression. Our unique technology and forward-leaning cyber investigation methods make an impactful combination, positioning eSentire to make a difference in the incident response market and most importantly --- enable enterprises to successfully counter today's more complex cyberattacks.” Sartin is an established InfoSec leader and influencer, having worked in the industry for more than 25 years. He comes to eSentire, most recently having spent 17 years with Verizon, overseeing the company’s security consulting, systems integration, breach response, and cyber intelligence functions worldwide. At Verizon, Sartin led a team of 600 cybersecurity experts, including consultants, cyber investigators, and researchers across 33 countries, driving service delivery in more than 110 countries. Sartin established the Verizon RISK Team in 2007, which has become one of the largest cyber investigations companies in the world, measured in case velocity, global reach, and unit sales. He also played a key role in creation of the annual Verizon Data Breach Investigations Report publications. Sartin has personally led more than 500 breach investigations for commercial enterprises and government agencies. He has testified in front of the U.S. House of Representatives and served as a fact witness in some of the largest, most publicly visible data breaches on record. Sartin has patents filed in security monitoring, intrusion detection, and network risk scoring. He is also a licensed, private security investigator and a qualified investigations company manager. Sartin majored in Management Information Systems and Finance at Rensselaer Polytechnic Institute (RPI). As organizations face a constant stream of cyberthreats from nation states and for-profit threat actors, they simultaneously find themselves challenged to find enough cybersecurity talent to fill crucial internal security roles. eSentire takes on that burden for organizations, stopping breaches, containing threats, and minimizing business risk. eSentire's MDR services are powered by eSentire’s Atlas XDR platform. It is the foundation for all eSentire multi-signal MDR services. eSentire provides customers with around-the-clock, proactive threat hunting across their networks, endpoints, cloud workloads and hybrid environments, eliminating blind spots traditional technologies miss and safeguarding all aspects of their business.
