Press release. Bitdefender has announced the global availability of GravityZone PHASR (Proactive Hardening and Attack Surface Reduction) as a standalone solution. In this way, this preventive security technology is now within the reach of any organization, regardless of the endpoint protection or detection platforms (EPP or EDR) it currently uses.
Bitdefender GravityZone PHASR is the industry’s first endpoint security solution that combines dynamic behavior-based hardening with real-time threat intelligence, proactively stopping ransomware attacks and living-off-the-land (LOTL) techniques. This new standalone release enables companies to easily add powerful preventative security capabilities and significantly reduce risk from excessive privileges, zero-day vulnerabilities, and third-party supply chain threats, without disrupting operations or replacing their already deployed EPP or EDR tools.
According to Gartner, “Traditional reactive cybersecurity is ineffective against sophisticated AI-powered threats that target the growing and connected global attack landscape. “AI-based preventive approaches, such as dynamic attack surface reduction (DASR), self-healing security, and adaptive trust, are essential to prevent these evolving threats.”.
The report adds that by 2030, 60% of large enterprises will use dynamic attack surface reduction technologies—up from less than 10% in 2025—to Proactively reduce your attack surface and mitigate cyber threat exposures.
This shift towards preventive defense is precisely what Bitdefender GravityZone PHASR offers. Based on years of innovation in machine learning and artificial intelligence, PHASR creates real-time behavioral profiles between users, devices and applications. Detects anomalies in application usage, privilege levels, and data access, automatically restricting only those tools and actions that deviate from known safe behavior. This gives security teams precise control that allows them to neutralize attacks before they escalate, even those that attempt to evade or disable EDR tools, without increasing IT complexity or impacting productivity.
GravityZone PHASR, features
- Advanced preventive security to existing environments – GravityZone PHASR, the first preventive security solution on the market within the new DASR category defined by Gartner, is available as a complement to any third-party EPP, EDR or XDR solution, without the need to modify current security configurations.
- Proactive prevention against ransomware and LOTL attacks – GravityZone PHASR dynamically restricts access to Living-Off-the-Land Binaries (LOLBins) and other legitimate tools commonly exploited in ransomware attacks, before they can be used maliciously. By tailoring defenses to each system, PHASR prevents attackers from reusing the same techniques in different environments, neutralizing repetitive attacks and dramatically reducing the risk of breaches.
- Drastically reduced attack surface and alert fatigue – GravityZone PHASR correlates user behavior with real-time threat intelligence and known attack vectors, defining the optimal security configuration for each user, reducing the attack surface without compromising performance. Its accuracy decreases unnecessary alerts, helping security teams operate more efficiently while achieving rapid and significant risk reduction with minimal effort.
“Enterprises face a new generation of stealth attacks that evade traditional defenses by leveraging trusted tools and applications already present in their own environments”said Andrei Florescu, president and general manager of the Bitdefender Business Solutions Group. “With PHASR now available as a standalone solution, we put our pioneering technology within the reach of all organizations, offering security teams a preventative, behavior-based defense that dramatically reduces risk without needing to modify their existing security operations.”.
