Donely
Donely provides Sentinel, an autonomous security agent that continuously tests applications like an adversary. The platform coordinates thousands of parallel AI agents to probe attack surfaces, then validates every finding with deterministic, production-safe exploit proof before reporting. Sentinel operates at machine scale, exploring attack paths monthly at rates orders of magnitude faster than human penetration testing.

Problem
Manual penetration testing covers less than 30% of the attack surface while automated scanners produce a median of 78% false-positive alerts. With code volume up 4x due to AI copilots and automated attackers probing every endpoint hourly, traditional security testing cannot keep pace with the speed or scale of modern application development and threat activity.
Solution
Sentinel is an autonomous security agent that continuously tests applications like an adversary. A persistent coordinator maps the attack surface, then directs thousands of short-lived, fresh-context AI agents in parallel, each focused on one objective such as SQLi, SSRF, IDOR, or business logic flaws. Findings are only surfaced after a deterministic validator reproduces them non-destructively, ensuring proof rather than probability. The system reports validated vulnerabilities with severity ratings and exploit evidence, operating continuously without human intervention at machine scale.
Target Audience
Primary customers are security teams, CTOs, and engineering leaders at SaaS companies and enterprises that need continuous, validated security testing across their applications, APIs, and cloud environments to keep pace with AI-accelerated development.
Features
- Persistent coordinator that holds a global view of the environment, plans attack paths, debriefs agents, and decides what to test next
- Thousands of parallel autonomous agents, each with a fresh context and narrow objective, avoiding context collapse and bias
- Integration with real offensive tooling including headless browser, Burp, ZAP, Nuclei, sqlmap, Semgrep, and custom payloads
- Deterministic validators that require each finding to pass controlled, production-safe exploit proof before leaving the platform
- Continuous testing that never sleeps, exploring attack paths monthly at a rate orders of magnitude faster than human pentests
- Live validation streaming with critical, high, and medium severity findings including exploit details like Blind SSRF via AWS metadata exfiltration and JWT alg=none acceptance
