Cybersecurity Startup Tenex Launches AI-Powered Cloud MDR Service

Tenex.AI Inc., a cybersecurity startup, has launched an AI-powered managed detection and response service today.

The company secured an undisclosed amount of funding from Andreessen Horowitz, Shield Capital, and a group of angel investors.

Tenex is led by its co-founder and CEO Eric Foster, who previously served as the president of Cyderes, a private equity-backed cybersecurity services firm. Elias Manousos, formerly vice president for security and threat intelligence AI products at Microsoft Corp., chairs Tenex's board.

Tenex's flagship offering is a managed detection and response (MDR) service tailored for Google Cloud environments. This service enables businesses to outsource some of their cybersecurity operations, thereby easing the workload on their internal IT teams.

Tenex addresses one of the most critical challenges in cybersecurity: inefficiencies in managing comprehensive security programs, according to Zane Lackey, a partner at Andreessen Horowitz.

The MDR service comes in three tiers. The basic version allows companies to have Tenex set up various cybersecurity systems and workflows within their Google Cloud environment. These include playbooks that automatically execute actions like file deletion when certain conditions are met.

After setting up the cybersecurity stack, Tenex assists clients in maintaining it and trains their internal IT teams to use the deployed technologies.

Customers opting for the two more advanced versions of the MDR service can leverage Tenex for more extensive involvement in their cybersecurity operations.

The top-tier Comprehensive MDR includes round-the-clock monitoring. Upon detecting malicious activity, Tenex’s cybersecurity experts take steps to remediate vulnerabilities and produce post-incident reports to help clients improve their security posture.

The Comprehensive MDR plan also features other components. Tenex helps clients maintain their detections, which are automated scripts designed to identify specific malicious activity patterns. Some organizations have hundreds of such detections, making internal management resource-intensive. Tenex also advises companies on emerging hacking threats targeting their infrastructure.

Tenex utilizes AI models to automate parts of the process of protecting client networks, reducing manual steps during vulnerability responses for quicker reactions. For vulnerability investigations, Tenex retains cybersecurity logs for 12 months.

Tenex's MDR product for Google Cloud environments went live earlier this month, with plans to introduce additional cybersecurity offerings later this year.

Lackey mentioned that Tenex may expand into areas like regulatory compliance, identity governance, and vulnerability management. Identity governance involves managing how employees and applications access corporate IT assets, while vulnerability management entails scanning for insecure configurations in IT environments.

It has been reported that Tenex is "open" to acquisition but intends to focus on organic growth in the near term.
