Penetration Testing
Our consultants define an authorized scope, validate exploitable weaknesses and provide practical remediation guidance.
- Networks, web applications, mobile applications and cloud environments
- An authorized scope agreed before testing begins
- Exploitable weaknesses validated, not just listed
- Practical remediation guidance for each finding
The challenge
From vulnerability list to attack path
A vulnerability list does not show which weaknesses can become an attack path. Penetration testing adds human analysis to identify combinations of weaknesses, validate practical impact and give remediation teams evidence they can prioritize.
What penetration testing means
A penetration test is an authorized, time-bounded assessment of agreed systems. Consultants examine how an attacker could enter, move through or misuse the environment without going beyond the written rules of engagement.
The scope can cover networks, web and mobile applications, APIs or cloud configurations. Results separate confirmed paths from theoretical concerns and explain both technical impact and practical fixes.
How far a tester can get
- Entry point. A reachable login, service or exposed setting gives a first foothold within the agreed scope.
- Foothold. Initial access is checked for what it reveals about accounts, trust and nearby systems.
- Pivot or escalation. A control such as segmentation or least privilege can stop movement toward higher access.
- Target asset. The sensitive data or system the engagement was scoped to protect stays out of reach.
Why it matters
- Business risk: Weaknesses stay unseen until someone with bad intent finds them, and fixes then happen under pressure.
- Decision it supports: Teams can decide which weaknesses to fix first, and which systems are ready for release or wider exposure.
- What you receive: A written report with reproducible findings, affected assets, severity reasoning and fix guidance for the agreed targets.
Testing shaped around the target
Web applications and APIs
Review authentication, authorization, input handling, business logic and data exposure.
- Why it matters
- Customer-facing applications often hold the data and transactions the business depends on most.
- Supports
- Decisions on application release and fix priority
Networks and infrastructure
Assess reachable services, configuration weaknesses, segmentation and privilege paths.
- Why it matters
- Flat or loosely controlled networks let one small mistake spread into a wider problem.
- Supports
- Evidence for segmentation and hardening work
Mobile applications
Examine application storage, communications, platform controls and supporting APIs.
- Why it matters
- Apps on staff and customer phones can leak data through storage or weak backend calls.
- Supports
- Mobile release and backend fix decisions
Cloud environments
Review identities, exposed services, permissions and configuration within the agreed tenant scope.
- Why it matters
- Cloud permissions drift easily, and one over-broad role can expose many resources.
- Supports
- Cloud access and configuration clean-up priorities
Evidence-led reporting
Document reproducible findings, affected assets, risk context and remediation guidance.
- Why it matters
- Findings only lead to fixes when engineers can reproduce them and managers understand the stakes.
- Supports
- Handover to engineering and management owners

Penetration Testing
Frequently asked questions
How is penetration testing different from a vulnerability scan?
A scan flags possible weaknesses. A penetration test adds human analysis to validate findings, examine business logic and show how weaknesses may connect within the authorized scope.
What must be agreed before testing?
Targets, exclusions, dates, permitted techniques, test accounts, data handling and escalation contacts should be recorded in rules of engagement.
Can testing be planned around critical services?
Yes. Timing, intensity and specific techniques can be adjusted around operational constraints, with higher-risk actions requiring explicit agreement.
What does the final report contain?
The report records scope, methods, evidence, affected assets, risk context and remediation recommendations, followed by a debrief for relevant stakeholders.
