What goes wrong without it
Is your application actually as secure as it looks?
Security gaps rarely show up during normal functional QA. They surface when someone goes looking for them, and the people looking are not always on your side. If any of these sound familiar, they're risks a properly scoped test finds before an attacker does.
06 risk categories we test for in every engagement
- 01
Injection flaws hiding behind a working demo
SQL injection, command injection and similar flaws routinely pass functional testing unnoticed, because the application still "works" for normal input. It takes a deliberate attempt to break input handling to expose how easily an attacker could reach your database.
- 02
Authentication that only holds up for honest users
Weak password policies, predictable session tokens or sessions that never properly expire let an attacker impersonate someone else entirely. Functional QA rarely catches this, because the login flow "works" for the tester using it as intended.
- 03
Sensitive data leaking without a single error
Unencrypted API responses, verbose error messages and improperly secured storage can expose customer data, credentials or internal system details without ever triggering an obvious failure anyone would notice.
- 04
Access controls that break with one changed parameter
Without dedicated testing, a user can often reach data or actions outside their permission level just by editing a URL parameter or an API request, an issue functional testing almost never catches.
- 05
A known vulnerability nobody has looked for
Third-party libraries and frameworks accumulate publicly documented vulnerabilities. IBM's 2025 breach research put the average global cost at $4.44 million, and healthcare breaches at $7.42 million, making an unpatched dependency expensive to leave unnoticed.
- 06
No proof for the audit or contract that needs it
Many B2B contracts, certifications and regulatory frameworks require documented evidence of security testing. Without it, you risk losing deals or failing audits, regardless of how secure your application actually is.

What we test
Our security testing services
Every engagement is scoped around your actual attack surface, not a generic vulnerability checklist. Here's what's covered.
API Security Testing
Testing REST and GraphQL endpoints for broken object-level authorization, excessive data exposure and improper rate limiting.
Vulnerability Scanning & Assessment
Automated scans across your application and infrastructure to surface known vulnerabilities, outdated components and misconfigurations.
Network & Infrastructure Security Testing
Assessing servers, firewalls and network configurations for open ports, weak protocols and services exposed to the outside world.
Authentication & Authorization Testing
Verifying that login flows, session management, password policies and role-based access controls cannot be bypassed or escalated.
Sensitive Data Exposure Testing
Checking for unencrypted data in transit, insecure storage and information leakage through error messages or response headers.
Source Code Security Review
Static analysis of your codebase to catch insecure coding patterns, hardcoded secrets and logic flaws before they reach production.
Third-Party & Dependency Risk Assessment
Auditing libraries, plugins and integrations for known CVEs and supply-chain risks affecting your application.
Cloud Configuration Security Review
Reviewing cloud storage, IAM permissions and infrastructure-as-code for misconfigurations that expose data or systems publicly.
Compliance-Focused Security Testing
Security testing mapped to frameworks such as PCI DSS, HIPAA, SOC 2 and GDPR, with documentation suited for audits.
Remediation Support & Re-Testing
Working directly with your developers to fix confirmed vulnerabilities, then re-testing to verify each fix actually closes the gap.
Ongoing Security Monitoring
Recurring scans and testing folded into your release cycle, so new vulnerabilities get caught before they reach production.

Proof of what's exploitable, not just a checklist
Anyone can run a scanner and hand you a list of CVEs. We focus on confirmed, exploitable findings, with a clear path to actually fixing them.
Book a free security assessment-
Manual testing, not just automated scans
Automated tools catch known patterns. Our testers manually probe business logic, access controls and edge cases that scanners consistently miss.
-
OWASP-aligned methodology
Every engagement is structured around the OWASP Testing Guide and Top 10 risks, giving you coverage that maps directly to industry standards.
-
Findings ranked by real business risk
Reports prioritize vulnerabilities by exploitability and impact, not just a CVSS score, so your team fixes what actually matters first.
-
Deep API and microservices coverage
We test authentication, authorization and data exposure across every endpoint, not just the user-facing parts of your application.
-
Verified remediation, not just reporting
We re-test every confirmed fix to verify the vulnerability is actually closed, not just patched on paper.
-
Built to run inside your pipeline
Security scans can run automatically in your deployment pipeline, catching new vulnerabilities before they reach production.
-
We sit alongside your developers
We walk your engineering team through every finding with proof of concept and fix guidance, not a PDF that gets filed and forgotten.
-
Support beyond the engagement
Ongoing scanning and periodic re-testing keep your security posture current as your application and its dependencies evolve.
How we work
Our security testing process
A structured process built to find real, exploitable vulnerabilities and verify they're actually fixed, not just look tested.
- 01
Scoping & Threat Modeling
We map the attack surface, critical assets and threat scenarios relevant to your application before testing begins.
- 02
Reconnaissance & Information Gathering
Mapping endpoints, technologies and exposed services to understand exactly what's reachable from outside your organization.
- 03
Automated Vulnerability Scanning
Running scanners across the application and infrastructure to surface known vulnerabilities and misconfigurations quickly.
- 04
Manual Penetration Testing
Testers manually attempt to exploit authentication, authorization, input handling and business logic the way a real attacker would.
- 05
Exploitation & Impact Validation
Confirmed vulnerabilities are validated with proof of concept to demonstrate real-world impact, not theoretical risk.
- 06
Detailed Reporting
Findings are documented with severity, evidence and step-by-step remediation guidance, in both technical and business-readable formats.
- 07
Remediation Support
We work with your developers to implement fixes, answering questions and clarifying findings along the way.
- 08
Re-Testing & Sign-Off
Every fixed vulnerability gets re-tested to confirm it's fully resolved before the engagement is closed out.

Client words
Trusted by teams that can't afford to guess about security
Our annual pen test usually came back clean from automated tools alone. Manual testing found a broken authorization flaw on one of our internal APIs that would have let any authenticated user pull another customer's account data. That finding alone justified the engagement.
We needed documented security testing for a HIPAA audit and expected a generic report back. What we got was a prioritized list of real findings with proof of concept, and our developers had the critical ones fixed within a week.
A dependency scan flagged a library with a known critical vulnerability that had been sitting in our checkout flow for months. We patched it the same day the report landed.
Questions, answered
Security testing FAQs
How much does security testing cost?
The cost depends on the application size, endpoints, infrastructure and testing depth required. A focused web application penetration test is simpler, while full-scope testing across web, API and infrastructure requires more work. Every engagement is scoped and quoted individually.
How long does a security testing engagement take?
A focused penetration test on a single application typically takes 1 to 3 weeks. Full-scope testing covering web, API and infrastructure, including remediation support, usually runs 4 to 8 weeks.
Is security testing really worth the cost?
IBM's 2025 breach research put the global average cost of a data breach at $4.44 million, and $10.22 million in the US specifically. A structured security test typically costs a small fraction of that, and it exists to make sure you never have to find out which end of that range applies to you.
Do you re-test after vulnerabilities are fixed?
Yes. Every confirmed vulnerability is re-tested after remediation to verify the fix actually closes the gap rather than just masking the symptom.
Can security testing be automated?
Automated scanning forms part of every engagement and can run on a recurring schedule, but the highest-impact findings, like broken access controls and business logic flaws, need manual testing that automation alone can't replace.
Can security testing be integrated into our CI/CD pipeline?
Yes. We configure automated security scans to run at key stages of your deployment pipeline, so known vulnerabilities and dependency risks get caught before code reaches production.
How do you report the vulnerabilities you find?
Every finding is documented with severity, affected component, proof of concept and step-by-step remediation guidance, ranked by real-world exploitability so your team knows what to fix first.
Does security testing affect application performance or uptime?
We coordinate testing windows and scope carefully so production environments aren't disrupted, and any tests with potential performance impact are scheduled or run against staging environments by default.
How do you handle testing at scale, across many endpoints or services?
We prioritize testing based on risk and exposure, focusing manual effort on the highest-value targets while automated scanning provides broad coverage across every endpoint and service in scope.
Do you provide ongoing security testing, not just a one-time test?
Yes. Our maintenance plans include recurring scans, periodic manual re-testing and monitoring for newly disclosed vulnerabilities in your dependencies as your application evolves.
What does the final security report include?
You get a report with every finding categorized by severity, supporting evidence, business impact and clear remediation steps, alongside an executive summary suited for stakeholders and compliance audits.
What support is available after the engagement ends?
Ongoing vulnerability monitoring, scheduled re-testing and a direct channel for questions as your application changes. Most clients move onto a recurring testing plan tied to their release or compliance cycle rather than a one-time test.
