Bitdefender, a global leader in cybersecurity, has announced that its GravityZone Proactive Hardening and Attack Surface Reduction (PHASR) technology is now available as a standalone solution. This move makes Bitdefender’s preemptive security capabilities accessible to organizations of all sizes, regardless of the endpoint protection (EPP) or endpoint detection and response (EDR) platforms they currently use.

With this standalone release, security teams can leverage PHASR’s advanced, behavior-driven defense to proactively minimize risks and prevent attacks before they can cause damage.

A New Era in Endpoint Protection

GravityZone PHASR is the first solution in the industry to merge dynamic, behavior-based security hardening with real-time threat intelligence. It is designed to prevent ransomware and living-off-the-land (LOTL) attacks proactively. By offering PHASR as a standalone option, businesses can integrate powerful preemptive security features without disrupting their existing EPP or EDR setups, avoiding the need for complex rip-and-replace strategies.

Gartner® notes that traditional reactive cybersecurity approaches are increasingly ineffective against sophisticated AI-driven threats targeting today’s interconnected global attack surfaces. Their research highlights that “preemptive AI-powered measures, including dynamic attack surface reduction, self-healing security, and adaptive trust, are crucial to mitigating these evolving threats.” Gartner predicts that by 2030, 60% of large enterprises will adopt dynamic attack surface reduction technologies—up from less than 10% in 2025—to proactively reduce attack exposure.

How PHASR Strengthens Security

PHASR leverages years of AI and machine learning innovation to monitor user, device, and application behavior in real time. It establishes behavioral baselines, identifies anomalies in privilege levels, data access, and application usage, and automatically restricts actions that deviate from established safe behavior. This ensures attacks are neutralized before they can bypass or disable EDR tools, without adding complexity or disrupting productivity.

Key Advantages of GravityZone PHASR Standalone:

Seamless integration with existing environments – PHASR can be deployed alongside any EPP, EDR, or XDR solution, providing first-to-market preemptive defenses without requiring modifications to current setups.

Proactive ransomware and LOTL protection – The solution restricts access to Living-Off-the-Land Binaries (LOLBins) and other legitimate tools commonly exploited in attacks, preventing repeated intrusion techniques and significantly lowering breach risk.

Reduced attack surfaces and alert fatigue – By correlating user behavior with threat intelligence, PHASR defines optimal security configurations for each system. This precision reduces unnecessary alerts, helping lean security teams operate efficiently while achieving high-impact risk reduction.

“Organizations are now facing highly sophisticated attacks that exploit trusted tools and applications within their environments,” said Andrei Florescu, President and General Manager of Bitdefender Business Solutions Group. “By making PHASR available as a standalone solution, we are giving security teams everywhere a preemptive, behavior-driven defense that reduces risk dramatically without requiring changes to their existing security operations.”
