Understand Your External Exposure with GravityZone EASM

The reality is simple: if you can’t see it, you can’t protect it. As organizations accelerate their digital transformation and expand their cloud presence, the number of internet-facing assets continues to grow, often beyond what security teams can see or control.

These assets form an ever-expanding external attack surface, including everything from forgotten subdomains and unpatched cloud services to expired certificates and vulnerable partner systems.

To help organizations and managed service providers (MSPs) mitigate these growing risks, Bitdefender launched GravityZone External Attack Surface Management (EASM) - a powerful new solution that delivers discovery, visibility, and control over the assets adversaries target first.

External Attack Surface Management Is Now Mission-Critical

The attack surface encompasses much more than just internal managed assets and their associated vulnerabilities and misconfigurations.

Today, it extends into new attack surfaces beyond endpoints and includes unknown, unmanaged assets or assets you didn’t know were vulnerable or exposed to the internet. Cloud workloads, misconfigured development environments, forgotten subdomains, or expiring certificates can become high-value targets and an easy way in for threat actors.

Security teams know this. In fact, the 2025 Bitdefender Cybersecurity Assessment Report surveyed 1,200 cybersecurity professionals, and 68% of respondents said that reducing the attack surface is a top priority in their security operations this year. Yet many struggle with visibility and manual asset inventory, which generates gaps in protection. Misconfigurations often go unnoticed until it’s too late, because security teams simply don’t know the asset exists.

Introducing Bitdefender GravityZone EASM: Proactive Visibility and Control

Bitdefender GravityZone EASM rewrites the rules through on-demand and scheduled scans, offering centralized visibility into all internet-facing assets. This reveals the attacker's external perspective and the weaknesses they could identify and exploit. Delivered as a seamless add-on to the Bitdefender GravityZone platform, EASM is agentless and built to scale, making it ideal for both enterprises and MSPs managing diverse customer environments.

Here’s how it works:

• Asset Discovery: GravityZone EASM scans IPv4/IPv6 addresses, domains, subdomains, IP blocks, and email accounts to map out your real-world exposure. It uncovers hidden, unmanaged, or obsolete assets in as little as 30 minutes.
• Vulnerability and Misconfiguration Identification and Management: It doesn’t stop at asset discovery. EASM identifies open ports, vulnerable public services, expiring/expired certificates, and more. Alerts are prioritized using context and CVE scores so teams can focus on what matters most.
• Unified Security, Risk and Compliance: Deeply integrated within GravityZone, EASM complements advanced Risk, Vulnerability and Patch Management, EDR, XDR, and compliance management. Security teams get a single pane of glass for risk analysis, policy enforcement, and exposure management.

EASM Advances Bitdefender’s Vision for Proactive Risk Management and Prevention

Expanded attack surfaces, growing compliance and IT complexity, and stealthy LOTL techniques, as well as AI-driven threats, make it necessary for organizations to adopt cybersecurity platforms that rapidly evolve to contain risks early and prioritize a proactive, prevention-first approach.

The Bitdefender GravityZone platform is recognized by industry analysts for its comprehensive risk analytics and prevention capabilities, which consistently lead independent testing. The recently launched GravityZone PHASR, GravityZone Compliance Manager, and now GravityZone EASM are rapidly advancing Bitdefender’s vision of enabling all organizations to proactively manage risks, effortlessly achieve compliance, and promptly respond to threats.

GravityZone EASM contributes to three key pillars that enable proactive risk management, helping customers stop attacks before they materialize.

• 360° Deep Risk Visibility: Properly securing the front door of an office building is not enough if a service entry and an open window remain unsecured. Comprehensive visibility of exposures is the first step to being able to effectively reduce risks and prevent attacks.
  
  GravityZone EASM complements the inside-out view of risks enabled by capabilities such as GravityZone Risk Management, Patch Management, PHASR, or CSPM+ by delivering the outside-in perspective, and identifying assets that are often unknown, unmanaged, vulnerable or misconfigured.
  
  
• Pragmatic Prioritization: Consider the same office building analogy: a faulty lock on a door that should be locked is something to be aware of, but if the door is already behind two other locked doors, the risk in this instance is low.
  
  GravityZone EASM reveals the vulnerable and misconfigured assets that are accessible from the internet. Just like an external-facing door, these risks typically need to be prioritized due to the speed and ease with which attackers can discover and exploit them. Additional CVE severity information helps organizations further refine their exposure prioritization.
  
  
• Automated or Simplified Remediation: In the real-world, the high effort of mitigating exposures is part of the reason why security gaps or attack entry points are sometimes not closed, despite the organization being aware of them. 
  
  GravityZone EASM facilitates management of discovered assets and for internet-facing assets that are managed by Bitdefender, it provides simplified or automated patching capabilities by leveraging Bitdefender GravityZone Patch Management.

Built for the Threat Landscape Ahead

Cybercriminals increasingly rely on automation to scan the internet for exposed or vulnerable systems. GravityZone EASM turns the tables—giving defenders the same level of insight into their external attack surface that adversaries already possess.

Conventional vulnerability management, which focuses primarily on known and managed endpoints, is no longer sufficient. Organizations need to adopt risk-based security programs and frameworks, such as Continuous Threat Exposure Management, to prioritize and address the exposures that matter most before attacks occur.

GravityZone EASM empowers organizations to transition from reactive firefighting to proactive risk management by illuminating the blind spots that attackers love to exploit. Whether you’re an enterprise security team or an MSP protecting clients, Bitdefender’s EASM is a powerful ally in the fight to reduce risk and reclaim control of your digital perimeter.
