Top 10 EASM Solutions for 2023

Top 10 EASM Solutions for 2023

The importance of External Attack Surface Management (EASM) has never been more evident. With cybercrime on the rise, 66% of organizations expect cyber budget growth in 2023. Meanwhile, estimates suggest that expenditure on cybersecurity products and services will reach $1.75 trillion by 2025. 

If you’re amongst those considering embracing EASM solutions to prevent external threats from catching you off guard, we’ll break down key features to look for in an EASM tool and highlight the top 10 EASM solutions for 2023. 

What is external attack surface management (EASM)?

EASM is a cybersecurity strategy that focuses on identifying and mitigating potential threats to a company’s digital assets that originate outside the organization–including various forms of phishing targeting customers or external parties and fraud through brand impersonation techniques such as clone phishing

EASM solutions continuously monitor a company’s external attack surface, including websites, domains, and social media accounts, to identify potential vulnerabilities and threats before they cause harm. While not a standalone measure, EASM helps companies get a more complete picture of their environment as enterprise attack surfaces are expanding, earning EASM technologies a leading position in cybersecurity trends recommended to CISOs by Gartner.  

Types of EASM tools

There are several types of EASM tools available, each designed to help users with different challenges:

  • Brand monitoring tools collect and analyze content from across digital channels to detect potential instances of brand abuse (such as fake domains and social media accounts created illegitimately under the brand’s name).
  • Website security tools can help users protect their websites from unauthorized access and attacks, including SQL injection, cross-site scripting (XSS), and Distributed Denial of Service (DDoS). 
  • Email security tools help users protect their email systems from various attacks, including phishing, spear-phishing, and whaling phishing. Most email protection tools monitor emails coming into the network using algorithms to parse for known malicious attachments, suspicious URL links, and malware. Some also feature virus and malware blocking, spam filtering, content filtering, and email archiving to help prevent users from opening and clicking on malicious content.
  • API security tools help to protect applications from external threats by monitoring and controlling their access through APIs. Users can leverage them to identify and block suspicious requests to prevent data breaches.

While these solutions alone may not be sufficient to address all EASM challenges, it’s common to combine them as part of an EASM strategy. 

Key features to look for in an EASM tool

When selecting an EASM tool, it is essential to consider the specific needs of your organization and look for the following key features:

  • Automatic inventory generation of exposed assets
  • Insights into business context and ability to understand the connections of each asset to the core network
  • Automatic asset classification
  • Automated, continuous monitoring
  • Risk prioritization and vulnerability management
  • Real-time alerts and reporting
  • Compliance and regulatory reporting

These features can help organizations discover, manage, and monitor their perimeter-less network at scale, providing visibility into their attack surface, reducing the risks associated with limited attack surface visibility, and improving the overall security posture of the organization.
