External Penetration Testing
A scan can tell you what might be exposed. Canary Trap validates what is actually exploitable across your internet-facing systems, then prioritizes what your team should fix first.
What we test, review, and validate.
Hands-on, senior-led testing supported by tools and threat intelligence, never replaced by them.
Outcome of this engagement
External exposure is not just a list of open ports or CVEs. Canary Trap combines manual testing, adversarial thinking, tools, and threat intelligence to assess what a real attacker could discover, validate, and exploit from outside your organization.
Discovery & footprinting
- External asset enumeration and OSINT
- DNS, subdomains, and exposed services
- Cloud-hosted edge and CDN exposure
Vulnerability validation
- Manual exploitation of identified weaknesses
- Authentication and access-control flaws
- Misconfigurations across edge, mail, and remote access
Attack-path analysis
- Chained vulnerabilities and pivot opportunities
- Likely initial-access vectors
- Risk to internal access from external exposure
A report your team can actually use.
A penetration test is only valuable if the findings lead somewhere. Canary Trap reports are written to support remediation, leadership visibility, compliance conversations, and customer or auditor requests.
Security confidence should come from how the application was tested
This engagement gives your team a defensible view of how your application behaves under adversarial use. You leave with evidence of what was tested, what was validated, where risk exists, and what should happen next.
A transparent process from scope to retesting.
Every application penetration test is scoped to your application, roles, workflows, timing, and testing objectives.
We confirm scope, testing objectives, rules of engagement, timing, contacts, and communication process.
Our testers identify, investigate, and validate externally exploitable weaknesses using manual testing, tooling, and relevant intelligence.
We document findings with evidence, severity, business context, and practical remediation guidance.
Your team addresses the findings with clear direction from the report and findings review.
We retest remediated findings within the defined window to validate that the risk has been addressed.
The proof behind this engagement.
External penetration testing is often treated like a commodity. That is usually where the trouble starts.
Canary Trap brings senior offensive security expertise, structured methodology, and practical reporting to help your team understand what is actually exploitable from the outside.
Senior-led testing
Testing is led by experienced offensive security professionals, not handed off to junior scanner operators.
Human-led validation
Tools support the process. They do not replace judgment. Our testers validate exploitability, investigate context, and look for realistic attack paths.
Practical reporting
Findings include the technical detail needed for remediation and the business context needed for leadership, compliance, and customer conversations.
Project management
Every engagement includes clear communication, defined expectations, and project management throughout the testing lifecycle.
Retesting and validation
Retesting helps confirm that remediated findings have actually been addressed, not just marked complete.
Trust signals
Canary Trap is SOC 2 Type II certified, maintains an NPS above 95, and specializes in offensive security testing.

External penetration testing questions, answered plainly.
External penetration testing evaluates internet-facing systems to identify and validate exploitable weaknesses that could be reached from outside the organization.
Canary Trap combines external vulnerability assessment, manual validation, attack-path analysis, reporting, and retesting to help teams understand and reduce external exposure.
Compare scope before you compare price. Ask each provider four things: who actually performs the testing and how senior they are; how much of the engagement is manual exploitation versus automated scanning; whether retesting of fixes is included or billed separately; and whether they’ll share a redacted sample report. The sample report settles most evaluations on its own — it’s the deliverable you’ll be defending to your auditor, your leadership, and your customers.
Cost is driven by scope — primarily the number of external IPs, applications, and exposed services in play. A small perimeter of ten to twenty-five public IPs is a materially different engagement than a multi-cloud estate. We price from scope, not from a rate card, and we’ll tell you honestly if a lighter-weight assessment is the better fit. If quotes you’re comparing vary widely, the scope varies — ask each vendor how much of the work is manual.
Most external engagements run one to three weeks of active testing, depending on the size of the attack surface. Scoping to final report typically fits inside a six-to-eight-week window. If you’re working backwards from an audit or renewal date, tell us the date on the scoping call and we’ll build the schedule around it.
Canary Trap coordinates testing windows, rules of engagement, and escalation contacts before testing begins. Destructive techniques are avoided, and testing can be paused immediately if required.
Yes. Our reports are written to support common compliance frameworks — and to remain technically useful to the engineering team that has to fix things. Compliance requirements are a floor, not the goal; a report that only satisfies your auditor has done half its job.
Yes. Retesting of remediated findings is included within a defined window after report delivery, so every fix is confirmed rather than assumed — and your evidence pack shows validated remediation, not just identified issues.
An executive summary, findings prioritized by exploitability and business impact, step-by-step proof of exploitation, practical remediation guidance, and retest results. Whoever you choose, ask for a redacted sample report before you buy — in this business, the report is the product.
A vulnerability scan identifies potential issues. External penetration testing validates whether those issues are exploitable, investigates business context, chains weaknesses where possible, and explains what should be prioritized.
Annually at minimum — but the honest answer is: whenever your environment changes in ways that create new exposure. New infrastructure, cloud migrations, acquisitions, and major releases all warrant testing. A penetration test validates your environment as it existed on the test dates. It doesn’t validate what you deploy next quarter.

A short scoping call is enough to align on your environment, timing, testing objectives, and the right next step.
