From vendors providing endpoint detection and response tools to companies offering managed detection and response services, here’s a look at key endpoint and managed security companies.

Coolest Endpoint And Managed Security Companies

Amid intensifying cyberthreats, the ability to detect malicious activity across endpoints and other IT environments is now table stakes for most businesses. Endpoint security continues to be one of the fastest-growing segments of the cybersecurity market, with revenue surging 27.1 percent between the end of June 2021 and the end of June 2022, according to IDC figures. The research firm noted that while the attack surface is getting bigger for businesses, the damage that attackers can do by targeting endpoints is accelerating as well.

In the $8.6 billion endpoint security market, the leaders by share of revenue are CrowdStrike, Microsoft, Trellix, Trend Micro, VMware, Sophos and ESET, according to IDC. Just a bit further down the list is SentinelOne — which, while it’s No. 10 on market share, generated the fastest year-over-year revenue growth of any endpoint security vendor in the top 10 with 109.3 percent growth. CrowdStrike held the No. 1 spot with revenue growth of 62.4 percent, compared to the prior 12 months, while Microsoft held onto No. 2 with 59.2 percent growth, IDC reported.

Increasingly, many endpoint detection and response (EDR) providers have broadened their offerings to provide what‘s known as XDR, or extended detection and response. XDR platforms correlate data from across an organization’s environments and devices, prioritize the most serious threats and then offer the ability to carry out a response automatically. XDR, a term coined by Palo Alto Networks founder and CTO Nir Zuk in 2018, is seen as an important development due to the fact that many cyberattacks today take place over a number of different systems within an organization. The platforms aim to tie together the data from each environment in order to give a fuller picture of what‘s happening. Gartner has forecast that 40 percent of organizations will have deployed an XDR platform by 2027, up from 5 percent in 2021.

Likewise, for organizations that are looking to have threat monitoring, detection and response managed on their behalf, the managed detection and response (MDR) side of the market is growing fast as well. Gartner expects 60 percent of organizations to be receiving remote threat disruption and containment services from MDR providers as of 2025, compared to 30 percent currently.

What follows are the 20 endpoint and managed security companies that made our Security 100 for 2023.
