Security Testing
Security testing looks for weaknesses in your applications and infrastructure the way a capable attacker would, then explains each finding in terms of business impact and the fix. Renvric scopes tests to your real risks, reports clearly, and retests, so remediation is verified rather than assumed.

What security testing is for
Security testing deliberately probes a system to find exploitable weaknesses before someone else does. It complements secure design and code review: those reduce the chance of flaws, testing checks whether any remain. The outcome is a ranked list of findings with evidence and remediation advice, not a certificate.
A test is a snapshot. Code, configuration and threats change, so testing works best when repeated and tied to release events.
Types of test and what each can see
Static analysis (SAST)
Scans source code for insecure patterns early and cheaply, but produces false positives and cannot see runtime configuration.
Dependency and container scanning
Matches libraries and images against known vulnerabilities; fast, and essential for supply-chain hygiene.
Dynamic testing (DAST)
Exercises a running application from outside to find issues such as injection or misconfigured headers.
Manual penetration testing
A skilled tester chains weaknesses, tests business logic and authorisation, and finds what tools miss.
Infrastructure and cloud review
Examines network exposure, identity and access policies, storage permissions and secrets handling.
Scoping decisions to settle first
- Which assets are in scope: applications, APIs, mobile apps, networks, cloud accounts or staff via social engineering.
- Black-box, grey-box or white-box: how much the tester knows in advance, which changes depth and cost.
- Test environment versus production, and what safeguards apply if production is touched.
- Rules of engagement: dates, source addresses, contacts, stop conditions and data handling.
- Authorisation in writing from the system owner and, where relevant, hosting providers.
Share the outcome you need and Renvric will recommend the smallest useful next step.
Where serious findings tend to hide
Business-logic and authorisation faults cause many of the most damaging findings and are the hardest for automated tools to see. Examples include one customer retrieving another's records by changing an identifier, a discount code that can be applied repeatedly, a password reset flow that leaks account existence, or an API endpoint that skips the permission check the interface applies. Manual testing with valid accounts at different privilege levels is how these are found.
How Renvric runs a test
Scope and authorise
Confirm targets, access, constraints and written permission.
Model threats
Identify what an attacker would want from this system and the likely routes.
Test
Combine automated scanning with manual exploitation, recording evidence for each finding.
Report
Deliver findings ranked by exploitability and impact, with reproduction steps and fix guidance.
Walk through
Explain results to engineers and decision makers, and agree a remediation order.
Retest
Verify fixes and update the report status.
What a good report contains
- An executive summary stating overall risk and the few issues that need attention first.
- Each finding with severity, affected component, steps to reproduce, evidence and recommended remediation.
- A clear statement of what was and was not tested, and the dates.
- Positive observations, so you know which controls worked.
- Mapping to a recognised reference such as the OWASP Top 10 or ASVS where useful.
Handling risk during testing
Testing can disturb live systems. Renvric aims to agree rate limits, test windows and a contact who can stop activity immediately. Findings and any captured data are treated as confidential, shared only through agreed channels and retained for a stated period. Renvric does not offer to certify compliance; reports can support your own audit evidence on request.
Costs and engagement
Cost follows scope: number of applications and roles, API surface, depth of manual work and retesting. A one-off test is common before a launch; periodic testing and continuous scanning suit products changing weekly.
Ask any provider for a sample report, tester qualifications and how they handle findings that need urgent notice.

Common questions
What is included in security testing?
Scoping and authorisation, threat modelling, automated scanning, manual testing of authentication, authorisation, input handling and business logic, a prioritised report with reproduction steps and remediation advice, a walkthrough, and retesting of fixes. Infrastructure and cloud configuration review can be added depending on scope.
Who is it suitable for?
Teams launching a new product or major release, companies answering customer security questionnaires, organisations that have never had independent testing, and those that have made significant architectural changes. It also suits regulated businesses needing periodic assurance evidence.
How long does delivery take?
Duration depends on the number of applications, roles and endpoints and on the depth of manual testing. Tests are time-boxed, followed by reporting and retest. Renvric proposes dates after scoping and avoids promising speed that would reduce depth.
What affects cost?
The size of the attack surface, number of user roles, whether source code access is provided, depth of manual testing, environment readiness, report requirements and retesting. Well-documented systems and a stable test environment reduce effort and avoid wasted tester time.
How does Renvric control quality and risk?
Through written scope and authorisation, agreed rules of engagement, a named contact able to stop testing, evidence-backed findings, review of reports before issue, confidential handling of data and retesting to confirm fixes. Limits of the test are stated in the report.
