Security questionnaires, compliance audits, and partner reviews all arrive at the same question: how well your API layer holds up. Relevant Software secures your APIs in code, release after release: we test every endpoint, close the findings in code with the engineers who found them, and map the results to the regime your auditor works from.
An API security assessment maps how each endpoint authenticates callers, authorizes access, and shapes the data it returns. Our engineers then rank every finding by business impact, so your team knows what to address first.
Testing turns each security requirement into a check your team can run again. Your endpoints get exercised per role and per permission, with abuse cases, malformed payloads, and boundary values covered alongside the expected paths.
Access control governs who reaches which record. Our engineers review your token flows, scopes, and object-level checks against the roles your product uses.
Every response your API sends decides how far sensitive data travels. The work sets field-level rules, masking, and encryption at the boundary where data leaves your systems, and those rules hold wherever the data goes next. Our data engineering team builds analytics pipelines as its own engagement, and the field-level rules set at the API boundary govern what any pipeline can carry into a warehouse.
Findings become working software here: the same engineers who tested your API write the fixes, and API development services carry the larger rebuilds when authentication or a data model needs redesigning.
Auditors ask for evidence in their own vocabulary, so every finding and fix arrives mapped to the control it satisfies under SOC 2, PCI DSS, HIPAA, or GDPR.
Manual testing puts your endpoints under the techniques a real attacker uses, covering REST, GraphQL, gRPC, and SOAP interfaces in black box, grey box, and white box models.
Live APIs earn attention after launch, so the work sets the logging, alerting, and abuse detection that show how your endpoints behave in production. Our cybersecurity team runs the detection and response across the wider environment those APIs sit in, from SIEM to endpoint coverage.
Your endpoints, environments, roles, and compliance drivers go through a short scoping call, and the output is a test plan naming what gets tested and when.
Discovery lists every endpoint that answers, including the deprecated and staging routes documentation tends to miss, so testing covers what runs.
Testers work through the OWASP API Security Top 10 by hand against each role, and business-logic findings surface here rather than in a scanner summary.
Each finding arrives with its reproduction steps, its business impact, and its place in a queue your engineers can work down.
Our engineers close the findings in your codebase as pull requests your team reviews, with regression tests holding each fix in place.
Every closed finding gets verified, and the final report plus evidence pack goes to your auditor, your board, or your client.
Your CI inherits the checks from the engagement, so each release after this one carries the same standard without another external pass.
ISO 27001, GDPR, and HIPAA-aligned delivery. Our own certified controls govern how your code, credentials, and findings get handled through the engagement.
Findings closed by the engineers who found them. Your developers keep their roadmap while the security work lands in code on our side.
99% of milestones delivered on time. Audit dates and client deadlines hold, because the test plan gets scoped against your calendar before work starts.
Open Banking, HL7 FHIR, and PSD2 delivery experience. Our team answers fintech and healthcare compliance questions from projects already shipped.
Relevant AI Delivery Framework™: up to 50% faster delivery through AI-assisted development, with every security fix still passing senior code review.
Your frameworks, your CI, your repository. Fixes arrive as pull requests in the codebase your engineers already maintain, with regression tests in the framework they already run, so the security work stays theirs after the engagement closes.
Pricing follows scope, and you can estimate yours from four variables: the number of endpoints in the test scope, the number of user roles the tests run against, whether the engagement includes remediation in code or stops at the report, and which compliance regime the evidence maps to. Remediation is the variable that moves the number most, and it is also the one that saves your engineers the most time. Relevant reviews all four with you on the first call and itemizes each in the proposal, with a test plan and a prioritized roadmap ready within 14 days.
A quick estimate you can run today: count your live endpoints and multiply by the number of roles that can call them, because that product, rather than endpoint count alone, drives the manual testing effort. If pulling that list together is the hard part, contact us and our team will build the inventory with you as the first step.
A focused assessment on a contained API surface typically produces a findings report in two to three weeks, and a platform-wide engagement covering many roles and environments runs longer. Where a deadline is fixed, our team scopes the first pass around the endpoints your auditor or client cares about most, so the evidence they need arrives first and the remaining surface follows.
Yes, we can secure what you already run. Discovery maps the endpoints, consumers, and authentication in place today, and API testing then works against the system as it stands, with no access to the original team required. Most findings close as targeted changes inside the existing codebase, and a rebuild enters the conversation only where an authentication model or data structure makes safe access impossible to express.
Yes, our engineers close the findings in code, and this is where our engagements differ from a testing-only vendor. The same people who found each issue write the fix as a pull request your team reviews, add regression tests that keep it closed, and wire the check into your CI. Your developers stay on their roadmap, and the security work reaches production on our side of the line.
Where your team prefers to own the fixes, we hand over reproduction steps, the recommended approach, and review support while your engineers implement.
Both models work, and the scope decides. For a single assessment or a compliance-driven test pass, a small group of senior security engineers fits and works alongside your team. For continuous coverage across many services, or where remediation runs alongside feature delivery, a standing team carries more of the load. If you would rather extend your own security function than buy an engagement, you can hire cybersecurity experts who join your team directly.
A signal for choosing: if a specific audit or client deadline is driving the work, start with a scoped engagement, and where APIs ship weekly across several teams, continuous coverage pays off faster.
Auditors want evidence tied to named controls, so each finding and each fix arrives mapped to the control it satisfies in your regime, and the retest report closes the loop with a date and a verification. That package covers the API portion of an audit, and the wider certification also asks for organizational controls such as access reviews and incident procedures.
A check you can run today: open your last audit report or client questionnaire and mark every line mentioning interfaces, integrations, or data transmission, because those lines are the API scope. If no audit has reached you yet, our team maps your endpoints to the regime you expect to certify under.
We secure your APIs in code, release after release, and hand you the evidence.
