Donely
donely.ai provides Sentinel, an autonomous AI security agent that continuously pentests applications like a human adversary. The platform combines creative AI discovery with deterministic exploit validation to deliver verified findings at machine scale, replacing manual penetration testing with always-on security coverage.

Problem
Manual penetration testing covers less than 30% of the attack surface while automated scanners generate a median 78% false-positive rate. With AI copilots increasing code volume fourfold and automated attackers probing endpoints hourly, traditional security testing approaches cannot keep pace with modern application attack surfaces.
Solution
Sentinel is an autonomous AI security employee that continuously pentests applications using a coordinated system of thousands of parallel agents. A persistent coordinator maps the attack surface, directs short-lived agents to pursue focused objectives like SQLi, SSRF, IDOR, and business logic flaws, then debriefs results. Every finding must pass a deterministic validator that reproduces the exploit non-destructively before it reaches the user's queue, ensuring proof rather than probability. The platform integrates real offensive tooling including a steerable headless browser, Burp, ZAP, Nuclei, sqlmap, and Semgrep, combining creative AI discovery with deterministic decision-making.
Target Audience
Primary customers are security teams, DevOps organizations, and application development groups at enterprises that need continuous, validated penetration testing coverage without the cost and limitations of manual security assessments.
Features
- Persistent coordinator that maintains a global view of the environment, plans attack paths, and decides what to test next
- Thousands of short-lived autonomous agents with fresh context that each pursue one narrow objective to prevent context collapse and bias
- Deterministic validators that reproduce every finding through controlled, production-safe challenges before release
- Integration with real offensive tooling including headless browser, Burp, ZAP, Nuclei, sqlmap, and Semgrep
- Continuous 24/7 operation exploring 28,000+ attack paths per month with 12x faster results than human pentests
- Live streaming of validated findings with severity ratings and exploit details directly to the user's queue
