External Vulnerability Assessment for UK Businesses
Find the weaknesses attackers can see from the internet.
SabreShield AI assesses your internet-facing infrastructure to identify exposed services, vulnerable software, insecure configurations and other weaknesses that could increase the risk of compromise.
Every assessment is conducted within an agreed, explicitly authorised scope and findings are prioritised with practical remediation guidance. Testing begins only after explicit written authorisation and agreed rules of engagement.
EXTERNAL ATTACK SURFACE
See your systems from an attacker's perspective.
Your public-facing infrastructure is constantly exposed to automated scanning, vulnerability research and opportunistic attacks.
An external vulnerability assessment identifies weaknesses across the systems that your organisation exposes to the internet so they can be addressed before they become an easier route into the business.
01
Exposed Services
Publicly accessible ports, remote access services, administrative interfaces and unnecessary exposure.
02
Known Vulnerabilities
Potential weaknesses associated with software versions, services and publicly documented vulnerabilities.
03
Security Misconfiguration
Weak TLS configuration, insecure services, unnecessary exposure and other configuration issues.
04
Attack Surface Changes
Previously unknown or newly exposed systems, services and infrastructure.
What we assess
- Domains and subdomains
- Public IP addresses
- Web servers
- VPN gateways
- Remote access services
- Email-related infrastructure where in scope
- Publicly accessible network services
- TLS and certificate configuration
- Exposed administration interfaces
- Cloud-hosted services where authorised
Final scope is agreed with the client before testing begins.
How the assessment works
Every stage operates within explicit written authorisation, the agreed scope and rules of engagement.
01
Scope
Agree exactly which systems, domains and IP addresses are authorised for testing. Record explicit written authorisation and rules of engagement.
02
Discover
Map the externally visible attack surface and identify exposed services.
03
Assess
Use recognised vulnerability assessment techniques and appropriate tooling to identify potential weaknesses.
04
Validate
Review significant findings to reduce false positives and determine practical relevance.
05
Report & Retest
Provide prioritised remediation guidance and retest material findings after fixes are implemented, where included in the agreed engagement.
More than a scanner report.
Automated scanners can generate large numbers of alerts without explaining which issues actually deserve attention.
SabreShield combines technical assessment with analysis and prioritisation so your team receives a clear picture of exposure rather than a raw list of scanner results.
01
Clear Severity
Findings prioritised by technical severity and likely business impact.
02
Useful Evidence
Evidence and context that helps technical teams understand and reproduce the issue.
03
Practical Remediation
Clear recommendations explaining what should be changed and what should be addressed first.
What you receive
A business vulnerability assessment should help decision-makers and technical teams act on the findings.
- Executive summary
- Technical findings
- Risk/severity rating
- Affected systems
- Supporting evidence
- Business impact explanation
- Remediation recommendations
- Prioritised action plan
- Retest status where included
Vulnerability assessment vs penetration testing
A vulnerability assessment identifies and evaluates potential security weaknesses.
A penetration test goes further by carrying out controlled attempts to validate whether selected weaknesses can be exploited within an explicitly authorised scope. Testing requires explicit written authorisation and agreed rules of engagement.
SabreShield can recommend the appropriate level of testing based on your systems, exposure and business requirements.

YOUR QUESTIONS, ANSWERED
External vulnerability assessment FAQs
What is an external vulnerability assessment?
An external vulnerability assessment identifies and evaluates potential security weaknesses in your internet-facing systems. Within an explicitly authorised scope, it reviews exposed services, software and configuration, then prioritises findings with practical remediation guidance.
Is vulnerability scanning the same as penetration testing?
No. Vulnerability scanning helps identify potential weaknesses and is one part of an assessment. A penetration test includes controlled attempts to validate whether selected weaknesses can be exploited. Both require explicit written authorisation and agreed rules of engagement.
Will the assessment affect our live systems?
Testing can carry a risk of disruption. Before work begins, we agree the scope, timing, permitted techniques, exclusions and stop conditions with you. We select proportionate checks and avoid activities outside the written authorisation; no assessment can promise zero operational impact.
How often should a business run a vulnerability assessment?
The right frequency depends on your exposure, rate of change and business requirements. Consider an assessment after significant infrastructure changes and agree a regular review schedule appropriate to your risk. Each engagement requires an up-to-date, explicitly authorised scope.
What systems can SabreShield assess?
The agreed scope may include domains, subdomains, public IP addresses, web servers, VPN gateways, remote access services, email-related infrastructure, TLS configuration and authorised cloud-hosted services. We confirm access permissions, ownership and any third-party restrictions before testing.
Do you retest vulnerabilities after they are fixed?
Retesting can be included in the agreed engagement to review material findings after remediation. The report records retest status where included. Coverage, timing and any additional work are agreed with you in advance.
Do you need written permission before testing?
Yes. SabreShield only performs testing with explicit written authorisation and an agreed scope and rules of engagement. These define the systems, permitted activities, timing, exclusions and escalation contacts. Any required third-party permissions must also be in place before testing begins.
Choose the right assessment for your systems
A vulnerability assessment UK businesses can act on starts with a clear understanding of their systems and priorities. Tell us about your organisation so we can agree a proportionate scope.
