Fast Company has named Astelia, an AI-native exposure management company, to its 2026 Next Big Things in Tech list. The startup was recognized in the On the Rise category for its efforts to address vulnerabilities using autonomous agents.
Why it matters
As AI models accelerate the speed at which attackers discover and exploit security gaps, traditional manual triage is struggling to keep pace. Astelia aims to bridge this capacity gap by automating the remediation of identified vulnerabilities.
Astelia employs AI agents to automate patching, segmentation, and configuration changes within enterprise networks. The company uses network context to determine whether a specific vulnerability is actually reachable, filtering noise for security teams.
The players
Astelia
An AI-native cybersecurity startup founded in 2024 that provides automated exposure management tools.
Fast Company
A business media organization that publishes annual lists identifying emerging technology and industry trends.
The details
The platform functions by mapping network context to identify potential attack vectors before they are targeted by external actors. It deploys AI agents designed to execute remediation tasks, such as patching or adjusting network segmentation, which limits the access paths available to a potential intruder. These agents are tasked with maintaining security posture without requiring constant manual intervention from security staff.
Timeline
2024: Astelia was founded by former leaders of the Israeli National Red Team.
October 6, 2026: The company was officially named to the Fast Company Next Big Things in Tech list.
The Tech Race
Astelia's founding team brings operational experience from the Israeli National Red Team, a background often associated with advanced offensive and defensive security research. The company is now applying this expertise to the crowded exposure management market by emphasizing full automation of vulnerability remediation.
Security teams can expect to see automated agents increasingly integrated into standard patching and configuration workflows. This shift aims to reduce the manual burden of triaging vulnerabilities, though it requires organizations to trust autonomous systems with critical infrastructure access.
The takeaway
Astelia represents the ongoing transition toward autonomous remediation in corporate security environments. Readers should watch for future technical disclosures regarding the specific reachability algorithms used to prioritize network patches.
