CEO Kerry Bailey has publicly stated that eSentire’s goal is to become “a billion-dollar company”.[1]

Business Highlights


eSentire is the largest pure-play Managed Detection and Response (MDR) company, leveraging proprietary technology and highly trained security analysts to detect, investigate and rapidly resolve cyber threats in customers’ hybrid IT environment made up of networks, cloud and applications.


eSentire delivers security-as-a-service called Managed Detection and Response (MDR), backed by a 24x7 Security Operations Center (SOC), staffed by security analysts who respond in real-time to threats before they become business disrupting events. eSentire also provides advisory services in different fields to a wide range of industries. Details on pricing are not available. The product segmentation is shown below.

  1. Managed Detection and Response (MDR): MDR services allow organizations to add 24/7 dedicated threat monitoring, detection and response capabilities via a turnkey approach.
  • esNETWORK: is the primary MDR’s sensor. It both detects unknown threats and respond real-time to cyber-attacks (i.e., phishing) using advanced behavior-based anomaly detection;
  • esENDPOINT: secures each endpoint of the client’s computer networks. This product is powered by Carbon Black;
  • esRECON: scans all the client’s devices in order to detect existing cyber threats;
  • esLOG+: uses advanced analytics and cloud-computing to identify known and unknown cyber-security patterns. These data are then elaborated by the Security Operation Center (SOC) analysts, who provide the clients with insights about cyber-security threats that have bypassed security technologies.
  1. Advisory Services
  • Virtual CISO: identifies existing gaps in the client’s security infrastructure and builds a solution accordingly;
  • Vulnerability Management: aimed at identifying strength and weaknesses of current client’s security infrastructure through a combination of tech and human tools/expertise (i.e., the penetration testing);
  • Risk Assessment: identifies risks in four main areas: organizational, programmatic, human, and technical;
  • Compliance: aimed at meeting the regulatory cybersecurity requirements of the client’s industry.


eSentire combines cutting-edge cyber-security technologies with expert security analysts. The company makes primarily use of the following technologies: cloud-computing (in partnership with Densify, Cyxtera, SumoLogic), advanced analytics, forensic investigation tools, and AI-based behavioral detection tool.


eSentire’s headquarter is in Cambridge (Ontario, CA). The New York office is responsible for the US market. London (UK) hosts eSentire’s EMEA HQ; the company has an additional European operations centre located in Cork (Ireland).


eSentire’s target customer is a mid-sized organization  operating across different business sectors, ranging from financial institutions to healthcare organizations.


eSentire's competitors offering cyber-security-related products and services are:

  1. Darktrace: (Cambridge, UK). It offers a comprehensive AI-based cyber defense. Given its wide cyber-security services offer as well as its presence in both UK and US, Darktrace can be considered one of the most prominent eSentire’s competitor.
  2. Endgame: (Arlington, VA - 2008). Endgame provides an endpoint security platform, thus being a threat for the esENDPOINT product.
  3. Security Compass: (Toronto, ON - 2005). Security Compass mainly provides cyber-security advisory services, thus being a threat for the several advisory services offered by eSentire.
