Trusted Web Application Penetration Testing

Serious Web Testing for Real-World Threats

Modern attackers don’t go through the front door — they slip in through your app. Whether it’s a login flaw, broken access control, or insecure business logic, a single vulnerability can put customer data, infrastructure, and trust at risk. Our job is to find those cracks before someone else does.

The Asteros Approach

We don’t dump scanner output into a PDF and call it a day. Every web application pentest we deliver is led by experienced security professionals using manual techniques — supported by automation, not replaced by it. We map out real risks, validate every finding, and deliver vulnerability assessments that speak clearly to your developers, your leadership, and your auditors.

Tailored guidance for your stack and team
Findings that matter — no false positives
Free retesting so you can prove progress

What You Get

Grounded in OWASP ASVS

We base our web application security testing on the OWASP Application Security Verification Standard (ASVS), a comprehensive framework for evaluating the security controls in modern applications.

Using the ASVS helps ensure that our assessments go beyond surface-level issues — we verify real, foundational security measures based on your app’s architecture and risk profile. Whether you’re working toward SOC 2, ISO 27001, or just want peace of mind, the ASVS gives us a proven, structured way to measure what matters.

Clarity, not confusion. Security you can show.

  • Actionable Results
    Every web application pentest we deliver comes with a high-signal report featuring step-by-step findings, risk ratings, and remediation guidance written for devs. You’ll also get an executive summary tailored for stakeholders — clear, concise, and safe to share.
  • True Coverage
    We don’t quit at “we got in.” We map the full path of risk — from login to escalation — showing you what’s working, what isn’t, and where to focus next.
  • Context That Clicks
    Whether you’re preparing for SOC 2, HIPAA, PCI, or just need a vulnerability assessment to improve risk visibility, we plug into your process without slowing your team down.

Use It for Compliance Too

Web penetration testing that holds up when it matters.

Asteros’ web application tests meet the needs of compliance frameworks like:

  • PCI-DSS (Req. 6.1 and 6.6)
  • SOC 2 (CC4.1 and CC7.1)
  • HIPAA & HITRUST (via risk evaluation)

We provide what auditors expect: detailed reports, clear validation, and a roadmap for remediation — with optional executive summaries for vendor security reviews.
