Penetration Testing Services in Palo Alto, CA

Serving SaaS Startups, AI Companies, and Compliance-Driven Teams in Silicon Valley

Based in the heart of the tech world, Palo Alto companies build the tools the rest of the world runs on. That means expectations — and risk — are high.

Asteros provides manual, standards-based penetration testing to help Palo Alto startups, SaaS platforms, and AI-driven teams reduce real-world risk, meet compliance goals, and build with confidence.

We’ve worked with clients in Palo Alto and across the Bay Area on:

• Web Application Penetration Testing — Focused, ASVS-aligned testing that goes beyond scanners to find logic flaws, auth bypasses, and other high-impact issues.
• Internal & External Network Infrastructure Testing — Internal and external assessments guided by PTES methodology, mapped to risk and attacker goals.
• Compliance Support — Reports built for SOC 2, ISO 27001, PCI-DSS, and vendor security reviews, with risk-rated findings, reproduction steps, and dev-ready remediation guidance.

Whether you’re prepping for a board meeting, landing your next big customer, or trying to keep up with investor expectations — we’ve got you.

Security testing for Silicon Valley SaaS and AI companies

Enterprise buyers now ask AI and SaaS vendors hard security questions before signing. We test LLM-integrated applications against the OWASP LLMSVS as well as the standard web application checks, so your report covers the AI section of the questionnaire as well as the rest.

How an engagement works

1. Scoping. A short call to understand your application, environment, and the deadline or framework driving the test.
2. Testing. Manual testing led by experienced testers. If we find something critical, you hear about it immediately, not at the end.
3. Delivery. One report written for your engineers, your auditor, and your customers’ procurement teams.
4. Retest. Once you have fixed the findings, we verify the fixes and update the report at no charge.

A typical engagement takes about two weeks. See pricing.

We work remotely, fast, and quietly — no drama, no filler, and no endless scanner dumps.
