Penetration testing & security assessment: Understand the risk. Prioritize the response.
Web applications, mobile apps, cloud environments and security advisory.
Assess exploitable weaknesses in the context of your business. Turn technical findings into clear remediation priorities and a defined path to verification.
A clearly defined engagement
- Written authorization before any testingSee step 3
- Scope, methods and testing windows agreed in advanceSee step 3
- Confidentiality and data handling defined before accessSee step 2
- Remediation verified through agreed retestingSee step 6
Evidence for your next security decision.
An assessment should give both technical teams and decision-makers a clear basis for action.
Understand the exposure
Document affected assets, supporting evidence and business impact so each finding can be assessed in context.
Prioritize remediation
Distinguish urgent issues from longer-term improvements, with practical recommendations for the teams responsible.
Verify the response
Record remediation outcomes through agreed retesting, including any remaining risk and follow-up actions.
Choose the assessment your decision requires.
Start with the systems you need to protect. Review the scope, approach and deliverables before discussing an engagement.
Web Application Penetration Testing
Validate exploitable weaknesses across web applications, APIs and business-critical workflows.

Authorization sets the boundary.
From initial scoping to verified remediation
A structured engagement with defined responsibilities, documented findings and an agreed path to follow-up.
- No testing before authorization
Scope the requirement
Establish the business context, proposed assets, assessment objectives and delivery expectations.
- No testing before authorization
Agree confidentiality
Define confidentiality and data handling before exchanging credentials, architecture or other sensitive material.
- Authorized
Confirm authorization
Verify authority and third-party permissions. Agree assets, methods, exclusions, testing windows and stop conditions in writing.
The letter states
- Scope
- Testing window
- Methods
- Authorized test window
Conduct the assessment
Perform agreed activities within the authorized scope, coordinate operational concerns and escalate significant findings.
Deliver the findings
Document evidence, impact and remediation priorities, with recommendations appropriate to the affected environment.
- Authorized test window
Verify remediation
Retest agreed findings after remediation and document their status, residual risk and any further action required.
Testing begins only after authorization is verified and the agreed conditions are in place. Scope changes or withdrawal of authorization require the affected work to pause.
Scope, responsibilities and follow-up arrangements are confirmed before work begins.
Clear responsibilities at every stage.
Scanning and vulnerability verification start only after valid written authorization.Engagement commitments 1 Work stays within the scope agreed by both parties.Engagement commitments 2 Confidentiality and data handling are agreed before sensitive information is exchanged.Engagement commitments 3 Deliverables focus on risk, remediation and verification.Engagement commitments 4
Engagement commitments
Authorization first
Targets, methods, testing windows and exclusions are agreed in writing before work begins.
Defined scope
Required cloud, hosting and other third-party permissions are checked first. Scope changes require fresh confirmation.
Confidential handling
The agreement defines access permissions, report recipients, retention periods and deletion arrangements.
Actionable findings
Reports explain impact and remediation. Retesting and follow-up are arranged under the project agreement.
Start with a clear assessment brief.
Share your organization, contact details and area of interest. We will use your request to discuss scope and next steps. No testing begins through this form.
Prepare your enquiry
- Describe your organization and select the relevant services.
- Review the authorization notice and confirm each acknowledgement.
- Review the prepared email, then send it from your email service.
How the engagement proceeds
Contact and verification
Discuss your needs and verify the representative’s authority, asset ownership and required third-party permissions.
Written agreement
Sign confidentiality, service and testing authorization documents covering scope, timing, risks, responsibilities and stop conditions.
Authorized testing
