External Exposure Audit Sprint
A timeboxed external attack surface assessment that identifies exposed internet-facing assets, misconfigurations, and security risks, with prioritized findings, evidence, and a remediation roadmap. Typical delivery is 3–5 business days after scope, prerequisites, and the start date are confirmed.
Typical range: $2,500–$7,500 depending on scope. Single-domain engagements start at $2,500.
Is this right for you?
This assessment is designed for organizations that need clarity on their external exposure without the complexity of a full penetration test.
Designed for
- Organizations preparing for compliance audits (SOC 2, ISO 27001, PCI)
- Engineering teams launching new public-facing infrastructure
- Companies needing external validation before a funding round
- IT leaders who want a second opinion on their security posture
- Teams that need documentation for leadership or board reporting
Not designed for
- Internal network penetration testing
- Continuous monitoring or managed security services
- Urgent breach response or incident investigation
- Social engineering or phishing simulations
- Organizations without clear asset ownership
What's included
Clear deliverables with fixed scope. No surprises.
Assessment scope
- Authorized domains, subdomains, and public-facing assets
- Exposure mapping: services, ports, misconfigurations
- Validation to reduce false positives
- Risk prioritization based on practical impact
Your deliverables
- Attack surface inventory with exposure notes
- Prioritized findings with evidence (screenshots, proof)
- Quick wins and longer-term remediation priorities
- Prioritized remediation roadmap
- Verification guidance where applicable
What this assessment does not include
- Internal network testing or authenticated scanning
- Exploitation of discovered vulnerabilities
- Social engineering or phishing simulations
- Ongoing monitoring or incident response
Need deeper testing? This sprint becomes the scoping foundation for a broader penetration test.
What we look for
The external-observable exposure vectors we map and validate during an engagement: what an attacker can discover and reach from outside your network.
Forgotten & shadow assets
- Legacy internet-facing servers
- Abandoned domains and subdomains
- Exposed staging and dev environments
Exposed services & remote access
- Open ports and admin interfaces
- Public RDP, SSH, and VPN portals
- Services reachable without authentication
Cloud & storage exposure
- Public storage buckets
- Misconfigured cloud services
- Publicly exposed dashboards
Encryption & headers
- Outdated or weak TLS/SSL
- Missing security headers
- Certificate and trust issues
Credential & info leakage
- Exposed API tokens and keys
- Leaked credentials in public sources
- Verbose errors and information disclosure
External Exposure Audit vs. Penetration Test
Two different questions. The audit maps what's publicly visible and reachable; a penetration test may validate attack paths within the written scope where conditions and safety permit. This engagement is strictly the former, non-intrusive by design.
| External Exposure Audit | Penetration Test | |
|---|---|---|
| Approach | Passive discovery plus bounded non-intrusive validation | Scope-bounded active testing; controlled exploitation where authorized and applicable |
| Exploitation | Not included | Conditional on scope, conditions, and safety |
| Lateral movement | Not included | Only where authorized and a foothold is safely established |
| Primary question | What is publicly visible and reachable? | Which attack paths can be safely validated within scope? |
| Delivery | Typical delivery: 3–5 business days | Typical delivery: 1–3+ weeks |
Need exploit-level proof? The audit is the scoping foundation for a focused penetration test.
How it works
Typical delivery is 3–5 business days after scope, prerequisites, and the start date are confirmed.
Scope Confirmation
We confirm authorized targets and sign the scope agreement. Discovery begins.
Validation
Findings are validated, deduplicated, and mapped to business-risk context.
Prioritization
Results ranked by severity and effort. Quick wins separated from strategic projects.
Delivery
Final report delivered, with an optional 30-minute findings review call.
Common questions
Will this trigger our security monitoring?
Our assessment uses standard external reconnaissance techniques (DNS, port scanning, SSL/TLS enumeration). If your SOC alerts on external scans, notify them in advance. We can coordinate timing and provide source IPs.
Do you need credentials or internal access?
No. This engagement is external-only. If findings indicate a need for authenticated testing, we'll propose a separate engagement.
What if we're not ready to fix everything immediately?
The remediation roadmap distinguishes near-term priorities from longer-term work so you can sequence remediation around risk, dependencies, and available resources.
What happens if you find something critical?
If we validate a critical finding, we notify you within 24 hours through the secure contact agreed at kickoff. Testing pauses if continued activity could increase risk.
Who provides external attack surface assessments?
Prox Offensive Information Security provides authorized, external-only assessments that map internet-facing exposure. Typical delivery is 3–5 business days after scope, prerequisites, and the start date are confirmed.
What's the difference between an exposure and a vulnerability?
An exposure is a state of visibility or reachability: an internet-facing asset, open port, or misconfiguration an attacker can discover from outside your network. A vulnerability is a weakness whose exploitability may require additional validation. An External Exposure Audit maps what is reachable and misconfigured; a penetration test may validate exploitability and attack paths within the written scope, where discovered conditions and safety constraints permit.
