What is security testing?

Security testing checks your software for weaknesses that attackers could use to steal data, take over accounts or disrupt your service. It combines automated scanning with manual testing by experienced testers, and ends with a clear list of what to fix.

What is the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment finds and ranks known weaknesses across your systems, mostly with tools checked by people. A penetration test goes further: testers try to exploit weaknesses and chain them together, the way a real attacker would, to show what could actually happen.

What are SAST and DAST?

SAST, static application security testing, reads your source code for security flaws without running it. DAST, dynamic application security testing, attacks the running application from the outside. SAST finds problems early; DAST finds what is exposed in practice. Most teams benefit from both.

Which standards do you follow?

OWASP Top 10, OWASP API Security Top 10, OWASP MASVS and MASTG for mobile, OWASP ASVS, PTES and NIST SP 800-115 for how tests are run, and CWE / SANS Top 25 for code. For compliance we map findings to SOC 2, ISO 27001, PCI DSS, HIPAA and GDPR.

Do you offer black-box, grey-box and white-box testing?

Yes. Black-box means we start with no inside knowledge, like an outside attacker. Grey-box gives us test accounts and some documentation. White-box includes source code and architecture. Grey-box usually gives the best value for the time spent.

Will testing break our live system?

We agree the scope, rules of engagement and testing windows in writing first. Risky tests run in staging where possible, and live tests are planned carefully with a named contact on call and a way to stop at any time.

How do you keep our data safe during testing?

We sign your NDA before access, use test accounts and synthetic data by default, and keep reports and evidence encrypted in transit and at rest. Findings are shared only with the people you name.

What will we receive?

A technical report with every finding, its severity rating (CVSS), proof-of-concept evidence and steps to fix, an executive summary for leadership, and a closure report after the retest.

Do you retest after we fix the issues?

Yes. Once your team has fixed the findings, we retest them at no extra cost and update the report to show which issues are closed.

Can you help us pass SOC 2, ISO 27001 or PCI DSS?

We don’t issue certificates, but we test the security controls those frameworks expect and give you evidence and reports that auditors and enterprise customers accept, along with a plan to close any gaps.

How often should we run security testing?

At least once a year and after major changes for penetration tests, quarterly for vulnerability assessments, and on every build for SAST and DAST checks in your pipeline.

Do you test mobile apps and APIs?

Yes. Mobile apps are tested against OWASP MASVS, including local storage, network traffic and reverse engineering. APIs are tested against the OWASP API Security Top 10, including broken access control, authentication and data exposure.

Can security checks run in our CI/CD pipeline?

Yes. We set up SAST, dependency scanning, secret scanning and DAST in Jenkins, GitHub Actions, GitLab CI or Azure DevOps, tune out false alarms and agree which findings should block a release.

[ 5 security testing services ]

From a first review to audit-ready evidence

Pick one, or combine them. Each service explains what we check, when you need it and the risk it prevents.

Security Testing

Full picture

A broad review of how your product stands up to attack: sign-in, permissions, data handling, configuration and the way all of it fits together.

The right starting point when you have never been tested, or when the product has changed a lot since the last review.

What we check

Authentication, sessions and password rules
Roles, permissions and access to other users’ data
Input handling, injection and file uploads
Security headers, TLS and configuration
