Draft:ESentire

From Wikipedia, the free encyclopedia
  • Comment: The tone of this draft is promotional. It does very little to help that lead contains empty editorial flourishes ("many XYZ ... and more") and the "products and services" section (relying entirely on the company's own website) reads like a sales brochure. While I've attempted to address some of it, in particular in light of the COI/PAID declaration, more needs to be tone to temper the clearly promotional intent.

History

[edit]

The company as founded in 2001 in Cambridge, Ontario by Eldon Sprickerhoff and Edmund Dengler, with an initial focus on providing cybersecurity services to hedge funds and private equity firms in the financial services sector[4]. The company’s name, derived from the word “sentry,” reflecting its mission to act as a continuous guardian against emerging cyber threats.

In 2008, eSentire introduced threat detection services, based on gathering real-time network telemetry and offered 24/7 SOC as a managed service to its customers. This service capability eventually led to what is now known as Managed Detection and Response (MDR) in the cybersecurity industry.

Throughout the following decade, eSentire expanded its operations beyond its Canadian base. In 2014, the company established offices in New York and London, UK, marking its entry into two of the world’s largest financial hubs[4]. In 2015, it opened a second Security Operations Center in Cork, Ireland[7].

eSentire announced growth equity investment from Warburg Pincus in Aug 2017. The investment used to accelerate eSentire's growth by expanding its technology services to existing clients and to enable it to reach more clients in new markets [8][9]. This fund enabled eSentire to acquires Cybersecurity AI leader Versive based in Seattle, Washington, US in late 2018[10]. By 2019 eSentire moved its HQ from Cambridge to Waterloo to adopt to the increasing number in its headcount [11].

In 2021, the company further extended with the acquisition of CyFIR, a digital forensics and incident response firm.[13]
