Penetration Testing
Find the flaws a
scanner can’t — before
an attacker does.
Tenendo replicates real-world cyberattacks by hand, uncovering the logic flaws, chained exploits, and misconfigurations automated tools miss — across your web apps, mobile apps, APIs, and infrastructure. You get findings ranked by real business impact, with clear fixes and a retest to confirm they hold.
Manual, adversary-led
CVSS-scored, prioritised
Retest included
Beyond a vulnerability scan
A scanner lists CVEs. A penetration test shows what an attacker could actually do.
Automated tools catch the known and the obvious. Real intrusions come from what they can’t reason about — business-logic abuse, chained low-severity issues, and human-shaped gaps. That’s what we test.
/ manual
Human-led testing
Experienced testers hunt for logic flaws, authorization gaps, and multi-step exploit chains that no scanner can find — thinking like the adversary, not a signature database.
/ prioritised
Ranked by real impact
Every finding is scored with CVSS and framed in business terms, so you fix what actually threatens your data and revenue first — not whatever a tool flagged loudest.
/ actionable
Fixes, then proof
Clear, developer-ready remediation for each issue — followed by a retest that verifies the fixes work and closes the loop with an attestation you can share.
What we test
Penetration testing across your whole attack surface.
Scope a single application or your entire environment. Each engagement is tailored to your stack, threat model, and compliance needs.
/Application
Web Application
- Vulnerabilities across every application layer
- Authentication and authorization mechanisms
- Session management and data handling
/Application
Mobile Application
- Security controls within the app interface
- Local storage and data-transmission risks
- Authentication, authorization, session handling
/Application
API
- Endpoints probed for flaws and misconfigurations
- Data validation and input/output handling
- Authentication, rate limiting, error handling
/Infrastructure
Internal Infrastructure
- Internal network controls and configurations
- Lateral movement and privilege escalation
- System and data access controls
/Infrastructure
External Infrastructure
- External-facing system flaws and misconfigs
- Perimeter defences, firewalls, IPS
- VPN, remote access, and cloud configurations
/Baseline
Vulnerability Assessmen
- Known vulnerabilities across systems and apps
- Outdated software and patch-management gaps
- Findings prioritised by severity and impact

How an engagement runs
A structured methodology — built on recognised standards.
Repeatable and transparent from kickoff to retest, so results are consistent, defensible, and easy to act on.
/ 01
Scoping & rules of engagement
Define targets, depth, and test type (black, grey, or white box), plus timing and safety boundaries to protect production.
/ 02
Reconnaissance & mapping
Enumerate and fingerprint the attack surface — services, endpoints, and assets — to plan where real risk concentrates.
/ 03
Testing & exploitation
Manual, adversary-style testing that validates vulnerabilities and chains them the way an attacker would, not just flags them.
/ 04
Post-exploitation & impact
Demonstrate real business impact — lateral movement, privilege escalation, data reach — safely and within scope.
/ 05
Reporting & prioritisation
Every finding scored with CVSS, explained in business terms, and paired with clear, developer-ready remediation.
/ 06
Retest & verification
Once you’ve remediated, we re-test to confirm the fixes hold and issue an attestation you can share with stakeholders.
- OWASP
- Top 10
- OWASP ASVS / MASVS
- PTES
- OSSTMM
- NIST SP 800-115
What you receive
A report your board and your engineers can both use.
01
Executive summary
Risk posture, key themes, and a prioritised roadmap in business language for leadership and the board.
02
Technical findings report
Every issue with CVSS score, evidence, reproduction steps, and impact — ready for the team to action.
03
Remediation guidance
Specific, developer-ready fixes for each finding, ordered so you close the highest risk first.
04
Retest & attestation
Verification that fixes work, plus a letter of attestation for auditors, customers, and partners.
Standards & compliance
Testing that stands up to auditors and regulators.

Engagements are structured to provide the evidence and documentation these frameworks expect from regular security testing.
Why Tenendo
An offensive team that reports like a partner, not a scanner.
Manual-led, not tool-led
Automated scanning is a starting point, never the deliverable. Our testers do the deep, creative work that finds the issues that matter.
Real-world adversary techniques
We replicate the tactics and tooling of genuine threat actors, so your test reflects how you’d actually be attacked.
Certified experts
Assessments are run by seasoned, certified specialists across application and infrastructure security.
Remediation-focused
We don’t stop at a list. Clear fixes, direct access to the testers, and a retest to confirm you’re genuinely more secure.
