Take control of your external attack surface

In the ever-evolving landscape of applications, Heyhack Recon stands out as a powerful ally. It's an indispensable tool for anyone overseeing the complex task of digital reconnaissance, offering a detailed exploration of your web assets while efficiently managing any potential risks to your infrastructure.

Starting with just a seed domain (e.g., your main corporate domain), Heyhack Recon automatically locates any other domains your organization has registered. It also dives into your public subdomains, identifies the servers operating within these spaces, and establishes all netblock owners of the IPs of your services. This information is all conveniently accessible through a user-friendly interface, enabling you to swiftly gain an overview and take charge of your external attack surface.

With its automatic discovery of exposed web servers across your Internet-facing domains, Heyhack Recon gives you the ability to mitigate potential risks proactively.

Avoid subdomain takeovers with active reconnaissance

Dangling DNS entries are a growing problem for many large organizations—particularly, for the organizations that have adopt the use of cloud-hosting providers such as Amazon Web Services, Microsoft Azure, Google Cloud Platform, Oracle Cloud Infrastructure, and others.

The fundamental issue revolves around the creation of DNS entries on critical domains (such as an organization's main corporate domain) that point to hostnames and IP addresses not owned by the organization itself.

If the organization release control of these hostnames/IPs (e.g., by the virtue of terminating a virtual machine in the cloud), a malicious hacker may create a resource in the cloud on the same host or IP that the DNS entry points to. In a matter of minutes, the hacker can take control of the subdomain and launch a wide variety of attacks, including phishing campaigns, cookie harvesting from unsuspecting visitors, reputational damage, and more.

Consolidate your service providers and strengthen your external attack surface

By fingerprinting each and every service exposed on your domains, Heyhack can automatically generate an overview of all the service providers you make use of and all the owners of the netblocks that host your services.

Most large organizations have engaged with a diverse selection of service providers that implement to varying levels of security. With Heyhack Recon, you can gain an overview of the external services you rely and develop a deliberate strategy with respect to the use of third-party service providers.

By consolidating the service partners you work with, you can not only boost the security of your external attack surface, but you can also reduce your spending on external providers (such as hosting partners, agencies, etc.).

Common questions about attack surface management

Here are some of the frequently asked questions around external attack surface management. If the points below don't answer the question you have, please reach out to one of our experts to set up a call. We'll be happy to help you clarify any question you might have. 🙂

What is external attack surface management?

External Attack Surface Management (EASM) is a key cybersecurity strategy that identifies and secures an organization's digital vulnerabilities, particularly in public-facing web applications. These often-targeted touchpoints, if left unprotected, can invite cyberattacks. EASM proactively guards digital assets, ensuring robust defenses in our connected era.

What does an external attack surface management solution do?

An External Attack Surface Management (EASM) solution proactively identifies, monitors, and secures an organization's digital vulnerabilities, especially in public-facing assets. Acting as a digital watchdog, it spots potential cyber risk areas, ensuring that public web applications and infrastructures remain resilient against emerging threats.

How do external attack surface management solutions work?

External Attack Surface Management (EASM) solutions employ advanced scanning and intelligence techniques to discover domains and services related to an organization. By harnessing big data analytics, domain intelligence, and IP tracking, they efficiently map out the digital landscape, pinpointing potential vulnerabilities in public-facing assets.

How does attack surface management work with pen testing?

External Attack Surface Management (EASM) and penetration testing are synergistic cybersecurity strategies. While EASM identifies and monitors an organization's digital vulnerabilities, especially in public-facing assets, penetration testing actively exploits these vulnerabilities to assess their risk. Together, they provide a comprehensive defense, ensuring robust security.

What role does an EASM solution play in application security?

An External Attack Surface Management (EASM) solution is pivotal in an application security strategy. Acting as the first line of defense, it identifies and monitors public-facing assets, highlighting vulnerabilities. This proactive approach complements other security measures, ensuring applications are both resilient to threats and optimized for performance.

How often should you scan your external attack surface?

For optimal security, it's advisable to continuously monitor your external attack surface. In today's dynamic digital landscape, threats evolve rapidly. Regularly scanning with an External Attack Surface Management (EASM) solution ensures timely detection of vulnerabilities, keeping your digital assets safeguarded and your reputation intact.

What role do web applications play in attack surface management?

Web applications are pivotal in External Attack Surface Management (EASM). Often being public-facing, they represent critical points of exposure. EASM emphasizes securing these applications against threats and breaches. By monitoring and fortifying web applications, EASM ensures a robust digital front, protecting data and maintaining business continuity.

How much does an attack surface management solution cost?

The cost of an External Attack Surface Management (EASM) solution varies based on factors like company size, number of domains and services to be covered, feature set, and vendor. Prices can range from approx. 5,000 USD per year to hundreds of thousands per year, depending on the vendor. Heyhack Recon is included in both the Professional and Enterprise plans.
