External Exposure & Attack Surface Management For DummiesAs your attack surface has grown to cloud infrastructures and across subsidiaries, attackers are looking for and finding unknown and unmanaged assets to serve as their entry points. More...
Exposure management (EM) is a cybersecurity practice that helps organizations identify and mitigate security risks in real time. It involves identifying access points, digital and physical assets that could be exposed to cyberattacks, mapping the organization’s attack surface, assessing risks, prioritizing and mitigating exposures, and continuously monitoring for new exposures. There are two core component of an exposure management strategy:
EM goes beyond reactive cybersecurity methodologies to help organizations understand how to respond to an attack and how to prevent one.
This is part of an extensive series of guides about data security.
While organizations can develop exposure management capabilities in-house, managed security service providers (MSSPs) are starting to offer exposure management services, providing everything from threat identification to assisting with remediation efforts. There are several types of emerging exposure management services:
The terms 'exposure' and 'vulnerability' are often used interchangeably in the context of cybersecurity, but they refer to different concepts.
Exposure refers to the state of being subject to potential harm from external threats. In other words, it reflects the possibility that an organization's systems may be attacked by cybercriminals.
Vulnerability refers to the weaknesses within the system that could be exploited by these external threats.
While it is important to fix vulnerabilities, it is equally important to understand and manage exposure. For example, the owner of a house in a risky neighborhood (equivalent to an exposure in cybersecurity) could take proactive measures like installing a security system or joining a neighborhood watch program, in addition to locking doors and fixing broken windows (equivalent to vulnerabilities). Exposures help an organization think more strategically about their cyber risks and take proactive action to reduce or mitigate them.
Scoping defines the boundaries of an organization's exposure management efforts. This step involves identifying critical assets, business processes, and potential attack vectors that need protection. Organizations determine the types of threats they face, assess their risk tolerance, and set objectives for exposure management.
A well-defined scope ensures that exposure management efforts remain focused and efficient. Organizations typically classify assets into categories such as cloud infrastructure, on-premises systems, applications, third-party integrations, and employee endpoints. Additionally, regulatory and compliance considerations, such as GDPR, HIPAA, or NIST frameworks, play a role in defining the scope.
Threat modeling is often used at this stage to anticipate attack scenarios and determine which parts of the organization are most at risk. By establishing a clear scope, security teams can align exposure management with business priorities and ensure that the most valuable assets receive the highest level of protection.
In the discovery phase, organizations conduct a thorough inventory of their attack surface, identifying all assets, systems, and applications that could be exposed to threats. This step includes external and internal discovery, covering known assets as well as shadow IT, unmanaged devices, misconfigured cloud services, and forgotten or abandoned applications.
Discovery methods include automated scanning, asset management tools, penetration testing, and manual security assessments. Organizations often leverage technologies like external attack surface management (EASM) and cyber asset attack surface management (CAASM) to gain visibility into their infrastructure.
The discovery process also involves tracking network connections, software dependencies, and third-party integrations that could introduce vulnerabilities. Since modern IT environments are dynamic, with frequent changes in infrastructure and software deployments, continuous asset discovery is essential to maintaining an up-to-date view of the attack surface.
Not all exposures pose the same level of risk. The prioritization step evaluates identified exposures based on their potential impact and likelihood of exploitation. Organizations consider several factors, including asset criticality, known threats, adversary tactics, vulnerability severity, and business impact.
To prioritize effectively, organizations use risk-scoring models such as the Common Vulnerability Scoring System (CVSS) and contextual risk assessment frameworks that incorporate real-world threat intelligence. This step helps determine whether a vulnerability is actively being exploited in the wild or if it remains a theoretical risk.
Security teams also assess the exposure window—how long a vulnerability has been present and whether security controls already mitigate some of the risk. By ranking exposures, organizations can focus resources on addressing the most critical risks first rather than attempting to fix every minor issue.
Validation involves testing and confirming the severity of prioritized exposures. Security teams use techniques such as penetration testing, red teaming, breach and attack simulations (BAS), and exploit proof-of-concept testing to determine whether identified risks can be leveraged by attackers in real-world conditions.
One key goal of validation is to eliminate false positives. Automated scanning tools may flag potential vulnerabilities, but not all findings represent an immediate or exploitable risk. By manually testing high-risk exposures, security teams gain a more accurate understanding of their security posture.
Additionally, validation helps refine risk assessments and improve response strategies. For example, if a vulnerability is difficult to exploit or requires extensive effort from an attacker, it may be deprioritized in favor of addressing a more easily exploitable issue. By validating exposures before remediation, organizations ensure that security efforts are directed where they are most needed.
Mobilization is the final step, where organizations take action to remediate or mitigate identified exposures. This step involves applying patches, updating configurations, implementing security controls, or deploying compensating security measures to reduce risk.
Remediation strategies depend on the nature of the exposure. For example, if a vulnerability is discovered in an application, security teams may deploy a software patch. If an exposed cloud service is found, they may apply access restrictions or update security policies. In cases where immediate remediation is not possible, alternative mitigations—such as network segmentation, threat detection rules, or zero-trust architecture—can be used to reduce risk.
Beyond technical remediation, mobilization also involves coordination between IT, security, and business teams to ensure that fixes are implemented without disrupting critical operations. Organizations may also update their exposure management policies, conduct security awareness training, and refine response playbooks to improve their long-term security posture.

One of the major benefits of exposure management is that it simplifies the process of risk mitigation. By identifying and assessing all potential points of exposure, it becomes much easier to prioritize and address these risks. Instead of reacting to threats as they emerge, organizations can proactively manage their risk exposure and reduce the likelihood of a successful cyber attack.
This proactive approach not only simplifies risk mitigation but also makes it more effective. By addressing potential points of exposure before they can be exploited, organizations can prevent many cyber attacks from happening in the first place. This can significantly reduce the potential impact on the organization, both in terms of financial loss and damage to reputation.
By reducing the likelihood of a successful cyber attack, organizations can ensure that their operations are not disrupted by such attacks. This is particularly important in the modern business environment, where even a minor disruption to IT systems can have a major impact on an organization's operations.
Furthermore, by identifying and addressing potential points of exposure, organizations can also reduce the potential impact of a successful cyber attack. For instance, by implementing robust backup and recovery procedures, organizations can ensure that they can quickly recover from a cyber attack and resume operations with minimal downtime.
Exposure management can also help organizations achieve tighter regulatory compliance. Many regulatory bodies now require organizations to have a robust cybersecurity strategy in place, and exposure management is a key part of this. By demonstrating that they are proactively managing their cyber risk exposure, organizations can not only comply with these regulations but also avoid potential fines and penalties.
Furthermore, by complying with these regulations, organizations can also enhance their reputation among customers, partners, and other stakeholders. This can provide a competitive advantage, as customers are increasingly concerned about the security of their data and are more likely to do business with organizations that take cybersecurity seriously.
Finally, exposure management can contribute to long-term sustainability. In today's cybersecurity environments, organizations that fail to manage their risk exposure are unlikely to survive in the long term. Exposure management can help organizations continue to operate and thrive, even in the face of growing cyber threats.
While exposure management provides a proactive approach to cybersecurity, organizations face several challenges in implementing it effectively:
Despite these challenges, organizations can improve their exposure management capabilities by leveraging automation, integrating threat intelligence, and adopting a risk-based approach to prioritization.
External attack surface management (EASM) is a foundational component of exposure management, which helps organizations identify and manage risks associated with Internet-facing assets and systems. The goal is to uncover threats that are difficult to detect, such as shadow IT systems, so organizations can better understand your organization’s true external attack surface.
EASM processes, tools, and managed services can help detect threats across servers, public cloud services, credentials, and third-party partners. Ideally, an EASM solution should help identify cloud misconfigurations, software vulnerabilities, exposed credentials, shadow IT, and various other security weaknesses that threat actors can exploit.
The first step in exposure management is identifying all assets that could be exposed to cyber threats. This includes digital assets like servers, applications, databases, and cloud services, as well as physical assets such as hardware and network devices. The identification process should also consider shadow IT assets—those not formally managed by the IT department but still connected to the network. Comprehensive asset inventories and continuous discovery tools are crucial to ensure all potential points of exposure are accounted for.
Once the exposed assets are identified, the next step is to map the attack surface. This involves creating a detailed visualization of all access points, interconnections, and potential vulnerabilities within the organization's IT environment. Attack surface mapping helps organizations understand how different assets interact and where security gaps might exist. This mapping should be dynamic, regularly updated to reflect changes in the environment, such as new deployments, updates, or configuration changes.
With a clear understanding of the attack surface, organizations can assess the risks associated with each exposure. Risk assessment involves evaluating the potential impact and likelihood of different types of cyber threats exploiting the identified vulnerabilities. This process often uses a combination of automated tools and expert analysis to assign risk scores to various exposures, helping prioritize which issues need immediate attention and which can be monitored over time.
After assessing the risks, the next step is prioritizing exposures based on their risk scores. Organizations should focus on high-risk exposures that pose the greatest threat to critical assets and operations. Prioritization helps allocate resources effectively, ensuring that the most significant threats are addressed promptly. This process should also consider regulatory requirements and business priorities, aligning cybersecurity efforts with overall organizational goals.
Mitigation involves implementing measures to reduce or eliminate the risks associated with identified exposures. This can include applying patches to fix vulnerabilities, reconfiguring systems to enhance security, implementing access controls, and using encryption. In some cases, it might involve removing or isolating high-risk assets. Effective mitigation strategies often combine technical solutions with process improvements, such as staff training and incident response planning, to enhance overall security posture.
Exposure management is an ongoing process that requires continuous monitoring to detect new exposures and changes in the threat landscape. Organizations should implement automated monitoring tools that provide real-time visibility into their security posture. These tools can alert security teams to new vulnerabilities, configuration changes, or unusual activities that might indicate a new exposure. The process then repeats in identification of exposed assets, assessing and prioritizing risk, and mitigating it.

In my experience, here are tips that can help you better enhance your exposure management strategy:
CAASM is a security solution that mainly addresses asset visibility and exposure. Via API integrations with existing tools, organizations can view all assets (both internal and external), query consolidated data, pinpoint vulnerabilities and gaps in security controls and address them.
CAASM and EASM both strive to enhance the visibility of an organization's assets and their associated threats. However, EASM focuses purely on external assets and identifies those assets through active internet scanning. EASM can be a data source to provide external visibility within CAASM.
Application security testing focuses on tools and resources used to identify weaknesses in software applications. EASM enhances AST by automating the identification process for insecure software, including applications not actively supervised by security teams. These can be services in use by developers, but unknown to security teams, software deployed in the past and currently unused, or public code repositories. Unprotected applications and APIs can pose potential threats to companies.
Cloud security solutions offer technologies to safeguard cloud-based workloads and data. EASM can empower these cloud security solutions by spotting an organization's assets across different cloud providers, thereby improving security management and governance in the cloud. This support is vital because, although cloud security solutions protect cloud properties effectively, they require organizations to be aware of their existing cloud assets.
Specifically, EASM complements Cloud Security Posture Management (CSPM) solutions. CSPM employs standard frameworks, enterprise policies, and regulatory requirements to proactively and reactively analyze and ascertain the risk/trust of cloud service configurations and security settings. In combination with EASM, CSPM can be used to protect cloud assets wherever they are deployed, even without the knowledge or permission of the organization.
DRPS helps to keep an eye on the surface web, deep web and dark web to detect potential threats to pivotal digital assets. It gives a detailed picture of how threat actors operate and the tactics they employ.
DRPS is mainly focused on threats to company's brands, customer information, data, and executives, preventing fraud, theft and impersonation attempts, while EASM has a wider asset discovery capability. Combining EASM and DRPS provides a more comprehensive overview of a company's digital assets and associated risks.
Vulnerability management platforms find, classify, prioritize, and coordinate the resolution or reduction of security issues in assets managed by the organization. EASM supplements vulnerability management by identifying risks deriving from an organization’s internet-visible assets and systems, including those that may not be well-managed by the organization or undiscovered.
