When it comes to cybersecurity, IT landscapes are complex, often untamed and inherently unpredictable. There are many known unknowns, and there are even more unknowns.
A lack of, or limited visibility over the organisation’s estate, is the root cause of many of the cybersecurity challenges organisations are facing today.
If there is no clear visibility over the IT estate, it is not possible to accurately validate potential threats or have any control over them. Only when visibility is clear can intelligence be wrapped around the known elements, enabling positive controls to be put in place.
The journey towards genuine visibility over your organisation’s cybersecurity estate starts with External Attack Surface Management—the crucial first step to transforming the unknown into the known.
External Attack Surface Management (EASM) is a systematic approach to the identification, analysis, and mitigation of vulnerabilities and risks associated with your organisation’s internet-exposed digital assets. From domains and web applications through to network infrastructure, EASM enables you to discover your organisation’s entire attack surface, including assets you may not know you have.
Threat actors will always take the path of least resistance, identifying areas of an organisation’s IT infrastructure where access will be easier, quicker, and have the least chance of detection. Attackers will look to access an organisation’s data, applications, and networks across various environments, including on-premise, cloud, subsidiary, third-party, or partner environments.
Highly distributed workforces, evolving IT infrastructure, and layers of legacy technology have left many organisations vulnerable to attack by a motivated adversary. Many are also working to a narrow definition of ‘attack surface’, neglecting SaaS applications, public cloud workloads, or third-party environments.
EASM is now a critical solution for SecOps teams. The objective is to know exactly what your attack surface reveals to an external threat actor—even over time, as your IT environment changes and evolves. Only by looking through an external lens, can you identify all potential points of entry an attacker might exploit to compromise your organisation’s security.
EASM gives you a holistic understanding of the security gaps you need to fill to fortify your organisation’s defences and reduce your overall risk.
BlueFort’s methodology is founded on Continuous Cyber Discovery – a technology-based roadmap to discover, maintain, automate and validate a single view of an organisation’s entire threat surface, delivering a comprehensive understanding of tools, assets, policies and APIs across on-premise, cloud and hybrid environments.
EASM is a critical component of Continuous Cyber Discovery involving two key steps:
First, we work to identify and catalogue all of your organisation’s business and IT entities, including any acquired companies or joint ventures, and any internet-exposed assets relating to those entities. Using artificial intelligence and machine learning, this process will identify and highlight any relationships and connections between entities and assets that may not already be visible or even expected, and how these put your organisation at risk. Connections like these can often be obvious to an attacker, even when they are not clear to the organisation itself.
The discovery phase will test your organisation’s entire attack surface – not just the IP ranges and assets you are already aware of. During this phase, organisations can find they have up to 30% more assets than they expected. This identifies a range of potential risks, gaps, and vulnerabilities that previously would have remained undetected – potentially indefinitely, or until a breach occurs. The process also uncovers and clarifies many of the shadow IT incidents that SecOps teams suspect exist within their organisation, but haven’t yet been identified.
A key benefit of the EASM discovery phase is applying business-level attribution to the risks identified. As assets and risks are uncovered, these are automatically and properly attributed to the correct business entity, function, area, or owner. This built-in context significantly increases remediation speed. Asset inventories include all external digital assets and identifying elements, from IP ranges and links, to web applications, certificates and software deployments.
Once we have a clear view of your organisation’s entire external threat surface, BlueFort will work with you to implement active security testing, dynamically deploying payload-based testing techniques across your external threat surface to identify vulnerabilities that real-world attackers might exploit.
Active testing identifies vulnerabilities with precision and provides a roadmap for remediation efforts.
Rather than simply highlighting issues, BlueFort will assess each area of concern to determine whether it poses an immediate threat, or if mitigating technologies are already in place. Prioritising vulnerabilities in this way – based on their potential impact – means remediation efforts can focus on critical vulnerabilities with the greatest potential for exploitation.
Understanding the severity of each vulnerability is essential for prioritised remediation. We ensure that your team can focus on the most critical issues that demand immediate attention, preventing the unnecessary allocation of limited resources to areas of lower risk.

External Attack Surface Management (EASM) provides a foundation for ongoing security controls
Active testing of the external attack surface is fast becoming a central focus for SecOps teams that realise effective visibility requires a transformational approach. As one of the only approaches to vulnerability management that addresses the ever-increasing sprawl of organisational IT environments, EASM ensures vulnerabilities are discovered and remediated quickly.
As things change within your organisation, EASM dynamically changes with it – automatically identifying and prioritising new vulnerabilities as your external attack surface evolves. It’s a solution that can continuously scale alongside your organisation and your security team – across cloud (SaaS, PaaS, IaaS), on-premise, subsidiary, third-party, or partner environments.
