Rapid7 Acquires Leading Web Application Security Provider, tCell

Boston, MA — October 15, 2018

Rapid7, Inc. (NASDAQ: RPD), powering SecOps through its visibility, analytics and automation cloud, today announced it acquired tCell.io, Inc., a leading provider of web application threat defense and monitoring. Through this acquisition, Rapid7 plans to expand its application security capabilities and help its customers better assess, monitor, and protect against application-based attacks.

tCell’s runtime application self-protection (RASP) and web application monitoring is expected to extend the capabilities of Rapid7’s Insight Platform by enhancing web application security at every level—from browser to server—helping organizations identify and block attacks. tCell was recognized as a strong performer in The Forrester New Wave™: Runtime Application Self-Protection, Q1 2018.

Rapid7's Insight Platform delivers a unique combination of network visibility, security analytics, and orchestrated automation used by organizations to manage risk, detect and stop attacks, and orchestrate security operations across their modern networks. In addition to web application security, Rapid7’s Insight capabilities include complete vulnerability management, security information and event management (SIEM), user behavior analytics (UBA), and security orchestration and automation (SOAR).

“Today’s fragmented ecosystem continues to be a challenge for security teams as they battle escalating threats while still supporting rapid innovation,” said Lee Weiner, chief product officer at Rapid7. “In order to address these issues, a practical and holistic view of application security is vital. tCell shares our vision for application security and we are thrilled to welcome them to the Rapid7 team. “

“Attacks on web applications are exploding as companies push out more applications faster and faster,” said Michael Feiertag, chief executive officer at tCell. “It was clear from the start of our conversations with Rapid7 that they understand this challenge and are committed to addressing it. We are incredibly excited to join the team and work together to deliver businesses the best possible application security solutions.”

The acquisition of tCell is not expected to have a material financial impact to Rapid7’s Annualized Recurring Revenue growth, revenue, and non-GAAP earnings (loss) per share for calendar year 2018, as guided on August 6, 2018.
