Precursor Security
External Attack Surface Management

Discover Your Attack Surface

EdgeProtect continuously discovers and monitors your organisation's external exposures: vulnerable software, misconfigured services, leaked credentials, expired domains, and high-risk vulnerabilities known to be actively exploited. Near real-time insights so you see changes to your attack surface before attackers exploit them.

Methodology

What EdgeProtect Analyses

Eight analysis modules covering your entire external attack surface, from email authentication and DNS records to exposed services, vulnerable software, and compromised credentials in public data breaches.

Email Security

Email Configuration Analysis

Checks for SPF, DMARC, and DKIM record presence and misconfigurations to ensure your organisation is protected against email spoofing and tampering attacks. Misconfigured email authentication is one of the most common enablers of phishing campaigns targeting your employees and customers.
Service Exposure

Exposed Services & Vulnerable Software

EdgeProtect identifies whether your organisation exposes software and protocols considered high-value targets for attackers, including unsupported and outdated software susceptible to known vulnerabilities. These exposed services provide a direct pathway into your network if left unaddressed.
DNS Hygiene

DNS Record & Domain Analysis

Checks for internal IP address disclosure and avenues for subdomain takeover. EdgeProtect also monitors domains associated with your organisation that have expired or are marked as available to purchase by resellers, preventing domain hijacking and brand impersonation attacks.
Threat Intel

High Risk Vulnerabilities

EdgeProtect identifies vulnerabilities associated with your organisation's assets that are known to be actively exploited in the wild by real-world threat groups. Findings are scored using EPSS (Exploit Prediction Scoring System) metrics alongside proprietary threat intelligence, ranking exposures by actual exploitation likelihood rather than CVSS scores alone. Your security team focuses on what attackers are actually using, not theoretical risk.
Breach Exposure

Service Configuration & Data Breach Analysis

Highlights common service misconfigurations that can be leveraged by an attacker, and analyses public data breaches to identify sensitive information relating to employees that could be used against your organisation. Compromised credentials from third-party breaches are one of the most common initial access vectors.
Engagement Pipeline

How It Works

From asset discovery to continuous monitoring and automated reporting.

Step 01

Reconnaissance & Asset Discovery

EdgeProtect maps your entire external footprint using automated reconnaissance: domains, subdomains, IP ranges, exposed services, and cloud assets. This includes shadow IT and forgotten infrastructure your team may not know exists, providing a complete inventory before scanning begins.

Step 02

Vulnerability Scanning

Continuous automated scanning across all discovered assets for vulnerable and outdated software, misconfigured services, expired domains, high-risk vulnerabilities, and exposed credentials. Scans run on a regular schedule so changes to your exposure are detected as they happen.

Step 03

Intelligence & Prioritisation

Findings are assessed using EPSS metrics and proprietary threat intelligence to rank exposures by severity, potential impact, and real-world exploitation likelihood. Actively exploited vulnerabilities surface first, ensuring remediation effort goes where it matters most.

Step 04

Instant Reporting & Remediation Guidance

Reports are generated immediately on scan completion with clear remediation recommendations. Track attack surface reduction over time and use automated documentation to demonstrate continuous monitoring to auditors, insurers, and board stakeholders.

Why Attack Surface Management?

You cannot protect what you cannot see.

Most organisations have more internet-facing assets than they realise: forgotten subdomains, shadow cloud instances, expired domains, and exposed services that never went through a security review. EdgeProtect discovers your full external footprint and monitors it continuously so nothing falls through the cracks.

Frequently Asked Questions

Common questions about this service, methodologies, and deliverables.

Attack surface management (ASM) is the continuous discovery, analysis, and monitoring of your organisation's internet-facing assets and exposures. This includes domains, subdomains, IP addresses, exposed services, vulnerable software, email configurations, and credentials leaked in public data breaches. The goal is to identify and remediate exposures before attackers find and exploit them.

EdgeProtect continuously monitors eight categories: email configuration (SPF, DMARC, DKIM), DNS records and subdomain security, exposed services and protocols, domain expiry and availability, vulnerable and outdated software, high-risk vulnerabilities exploited in the wild, service misconfigurations, and public data breach exposure for your employees.

Penetration testing is a point-in-time manual assessment where ethical hackers actively exploit vulnerabilities. Attack surface management is continuous automated monitoring that discovers and tracks your external exposures 24/7. They are complementary: EdgeProtect identifies what is exposed, and penetration testing validates how those exposures can be exploited. Most organisations benefit from both.

EdgeProtect cross-references vulnerabilities found on your external assets against real-world threat intelligence feeds that track which vulnerabilities are actively exploited by threat groups. This means your security team can prioritise remediation based on actual attacker behaviour, not just CVSS scores.

EdgeProtect analyses publicly disclosed data breaches to identify whether employee credentials, email addresses, or other sensitive information associated with your organisation have been compromised. Leaked credentials are one of the most common initial access vectors used by attackers, particularly for credential stuffing and password spraying attacks.

Yes. EdgeProtect discovers internet-facing assets associated with your organisation that may not be managed by your IT team: forgotten subdomains, cloud instances spun up outside of standard processes, expired domains still linked to your brand, and exposed services on infrastructure your team may not know exists.

EdgeProtect runs continuous automated scans of your external attack surface. New findings are reported as they are discovered, and detailed summary reports are delivered on a regular schedule. This ensures you have near-real-time visibility into changes to your exposure.

EdgeProtect complements internal vulnerability scanning by providing an outside-in view of your organisation. Traditional vulnerability scanners operate from inside your network. EdgeProtect shows you what an attacker sees from the internet: exposed services, misconfigured DNS, leaked credentials, and vulnerable software visible externally.

EdgeProtect supports compliance programmes by providing documented evidence of continuous external monitoring. Automated reports demonstrate proactive security posture for ISO 27001 (asset management and vulnerability management controls), Cyber Essentials (boundary firewalls and internet gateways), and cyber insurance underwriter requirements for attack surface visibility.

Yes, and we recommend it. EdgeProtect provides continuous visibility between annual penetration tests, identifying new exposures as they appear. Penetration testing then validates the most critical findings through manual exploitation. Together they provide both breadth (continuous monitoring) and depth (manual testing).
