Questions

How often should a SaaS do a penetration test?

At least once a year, and after any major change to authentication, payments, data model or infrastructure. Enterprise customers typically ask for a test dated within the last 12 months. Many of our clients pair an annual pen test with quarterly automated scanning on a retainer.

What does a pen test report include?

An executive summary, scope and methodology, a findings table with severity ratings, and for each finding the affected component, reproduction steps, evidence, business impact and a recommended fix for your specific stack. After the retest we add a closure status per finding and an attestation letter.

Black box, grey box or white box: which should I choose?

Grey box (test accounts, no source code) for most pen tests, because it models a logged-in attacker and gives the best coverage per dollar. White box (full source and config access) for audits and pre-launch reviews. Black box only when you specifically want to simulate an outsider with no knowledge.

Can you test a Next.js or React Native app?

Yes. We build on both, so we test the things generic vendors miss: server action authorization, client-exposed environment variables, middleware bypasses, deep-link handling, insecure local storage on mobile, and API authorization across roles.

Are your testers certified?

Ask us about our team's credentials and we'll share them directly, along with sample reports. We don't list certifications on this page; the report and the retest are what your auditor or enterprise buyer will actually evaluate.

How do we start?

Contact us with the URLs or apps in scope, the number of user roles and any deadline (a customer questionnaire, an audit date, a launch). We reply within 24 hours with a scope and fixed quote. Email hello@reliabuilds.com or WhatsApp +880 1705 646545.

The full guide

What cybersecurity services do we offer?

We offer four things: penetration testing of web apps, APIs and mobile apps; security audits of code and configuration; secure architecture reviews before you build; and compliance readiness for SOC 2, ISO 27001 and GDPR. Each produces a written deliverable your engineers can act on and your customers or auditors can read.

Service What we test or review Deliverable Typical timeline
Penetration test (web, API, mobile) Authenticated and unauthenticated testing against OWASP Top 10 and the OWASP API Security Top 10 Report with severity-rated findings, reproduction steps, fixes; retest and attestation letter 1-3 weeks
Web application security audit Source code, dependencies, auth and session logic, cloud configuration, secrets handling Prioritized findings, fix plan, dependency upgrade list 1-2 weeks
Secure architecture review Proposed or existing design: data flows, trust boundaries, auth model, infrastructure Threat model, design recommendations, checklist for the build team 3-5 days
Compliance readiness (SOC 2, ISO 27001, GDPR) Controls gap analysis against the framework you're targeting Gap report, remediation roadmap, policy templates, evidence checklist 2-4 weeks

Because we also build web products, our findings come with fixes, not just screenshots. If you'd rather we fix what we find, that's a separate fixed quote.

Findings come with fixes: the team that tests your product can also patch it.

How is a penetration test priced for a startup?

Every engagement is a fixed scope and a fixed quote after a scoping call, usually within 24 hours of it. We don't publish a rate card because the price is set by the attack surface, not by a package: the number of endpoints and user roles, whether mobile is in scope, and whether a retest has to land before a deadline. A retest of fixed findings is included in every pen test.

What sets the scope Why it moves the quote What you get regardless
Number of endpoints and screens Each one is tested per role, authenticated and unauthenticated Severity-rated findings with reproduction steps
Number of user roles Access-control testing grows with every pair of roles Fixes written for your stack, not generic advice
Platforms in scope (web, API, mobile) Mobile adds device storage, deep links and binary checks Same-day report of critical findings
Deadline A customer questionnaire or audit date may need a compressed window Retest of fixed findings and an attestation letter
Grey, white or black box White box adds code review time; black box adds reconnaissance Walkthrough call with your engineers

We scope tightly, which is why a startup can afford to test before the enterprise deal rather than after. Ongoing security (quarterly tests, scanning, advisory) runs as a monthly retainer sized to the hours you need.

Pen test vs vulnerability scan: what's the difference?

A vulnerability scan is automated software that matches your system against known issues; a penetration test is a person actively trying to break in using the scan output plus manual techniques the scanner can't do. Scans find outdated libraries and missing headers. Pen tests find broken access control, business-logic flaws and chained attacks.

Vulnerability scan Penetration test
Who does it Automated tool Security engineer, with tools
Finds Known CVEs, misconfigurations, missing headers Logic flaws, access control bypasses, injection, chained exploits
False positives Many Verified and reproduced
Output Long list Prioritized report with proof and fixes
Cost Low monthly subscription Fixed quote per engagement, scoped by endpoints and roles
Satisfies auditors or enterprise buyers Rarely on its own Usually required

We run scanners in every test, but the value is in the manual work.

What does a web application security audit cover?

The audit covers the OWASP Top 10 categories, your authentication and session design, dependency risk, cloud and CI configuration, and how secrets and personal data are handled. We review code and infrastructure together because most real breaches cross both.

6steps in every penetration test engagement

The OWASP Top 10 (2021 edition) categories we test against:

  1. Broken access control (the most common finding in the apps we see)
  2. Cryptographic failures
  3. Injection (SQL, NoSQL, command, template)
  4. Insecure design
  5. Security misconfiguration
  6. Vulnerable and outdated components
  7. Identification and authentication failures
  8. Software and data integrity failures
  9. Security logging and monitoring failures
  10. Server-side request forgery

For Next.js, React Native and Node.js applications we add framework-specific checks: server action and route handler authorization, environment variable exposure to the client bundle, middleware bypasses, JWT handling, Stripe webhook verification, and rate limiting on auth endpoints. For AI features we test prompt injection, data leakage through model outputs and tool-call permissions.

Do you need a pen test for SOC 2 or ISO 27001?

SOC 2 does not require a penetration test by name, but auditors expect evidence of vulnerability management and almost every enterprise security questionnaire asks for a recent third-party pen test. ISO 27001 requires technical vulnerability management (control A.8.8), which a pen test is the standard way to evidence. For both, an annual test plus retest is the practical baseline.

Our SOC 2 readiness work comes before you engage an auditor. We map your controls to the Trust Services Criteria, hand you a gap report, remediation roadmap and policy templates, and run the pen test that becomes evidence. If you already use Vanta, Drata or Secureframe, we feed their evidence collection rather than duplicating it.

How does a penetration test engagement work?

Every engagement follows six steps with a fixed scope and quote agreed up front and a written rules-of-engagement document before any testing starts.

  1. Scoping call. What's in scope (domains, APIs, apps, roles), what's out, test accounts needed, deadline. You get a fixed quote within 24 hours.
  2. Rules of engagement. Written agreement on testing windows, data handling, emergency contacts and what we will not do (no denial-of-service, no social engineering unless agreed).
  3. Testing. Automated scanning, then manual testing by role. Critical findings are reported the same day, not held for the final report.
  4. Report. Executive summary for non-technical readers; per-finding severity (CVSS), reproduction steps, evidence and specific fixes for your stack.
  5. Fix support. A walkthrough call with your engineers. Optional: we implement the fixes on a separate quote.
  6. Retest and attestation. We verify fixes and issue a letter you can share with customers and auditors.

Testing never includes denial-of-service techniques, and where possible runs against staging with production-like data. See products we've built and secured on the projects page.
