Top 10 EASM Solutions for 2025

The expansion of your attack surface is inevitable. As your business grows, so does the need to leverage API integrations, third-party services, and cloud-based tools to remain competitive. But what about ensuring that your product remains secure?

According to the Verizon 2025 DBIR, third-party involvement in breaches has doubled from 15% to 30% year over year. Attackers increasingly target the weak links in your interconnected systems, not just your core data.

You can’t stop growing to avoid risk. But you can deploy solutions that help you identify, monitor, and protect your external attack surface in real time.

What is External Attack Surface Management (EASM)?

External Attack Surface Management (EASM) is a cybersecurity practice that continuously identifies and mitigates potential threats to your digital assets outside the firewall. It monitors domains, websites, APIs, cloud infrastructure, and social platforms to detect vulnerabilities and stop external threats before attackers exploit them.

Many security teams are familiar with traditional perimeter defenses, but as digital ecosystems expand, EASM provides essential visibility where older approaches fall short.

Types of EASM tools

Different types of tools work together to provide a complete EASM strategy:

Brand Monitoring Tools

• Detect brand abuse such as fake domains and fraudulent social media accounts.
• Monitor digital channels for unauthorized use of brand assets.

Website Security Tools

• Protect websites from attacks like SQL injection, XSS, and DDoS.
• Monitor web applications for vulnerabilities and unauthorized changes.

Email Security Tools

• Detect and block phishing and spoofing attacks.
• Filter malicious attachments, suspicious URLs, and malware.

API Security Tools

• Protect APIs from unauthorized access and abuse.
• Monitor API traffic for anomalies and potential data breaches.

Combining these capabilities provides comprehensive protection across your external digital ecosystem.

Key features to look for in an EASM tool

When evaluating EASM tools, security teams should consider the following:

• Automated discovery of exposed assets.
• Business context insights to understand asset relationships.
• Automatic asset classification for improved visibility.
• Continuous monitoring for real-time compliance.
• Risk prioritization and vulnerability management.
• Real-time alerts and actionable reporting.

These features help organizations improve their visibility and resilience across the growing attack surface.
