Bitdefender Achieves Unparalleled Testing Results in VBSpam Benchmark

Bitdefender’s GravityZone email threat protection technology has been at the forefront of the industry for over a decade, and new independent test results validate this once again. We’re the only provider to have appeared in every VBSpam test to date, now at 80 rounds at the time of publication. In the past five years, our solution has amassed more number one positions than any other provider.

Bitdefender email security is both effective and consistent.  

According to VBSpam: “Since the introduction of the VBSpam+ certification – awarded to products that achieve a spam catch rate of 99.5% or higher with zero false positives – Bitdefender has further distinguished itself: out of 63 opportunities to date, the vendor has earned the VBSpam+ accolade an impressive 56 times.” 

The most recent tests reveal ongoing success. “Over the past year, Bitdefender GravityZone Premium has consistently ranked among the top three products based on final score, ranking in first place in both the Q1 and Q2 2025 tests,” VBSpam says.

Earning top scores in independent tests confirms why Bitdefender customers see positive security outcomes related to email-based threats. Our email threat protection technology delivers the following:  

• Comprehensive Email Security: GravityZone Security for Email provide businesses with ultimate threat detection and protection against targeted email attacks, with virtually no false positives, as the test results confirm.
• Stops Top Threats: It defends against spam, viruses, ransomware, and phishing, while also stopping non-malware threats like credential theft, business email compromise (BEC), CEO fraud, and more.
• Puts You In Control: A powerful policy engine with extensive customization options gives you complete control over mail flow. The module works seamlessly with all email service providers and hybrid setups—including on-premises Microsoft Exchange Server, Microsoft Exchange Online, Microsoft 365, and Google Workspace. 

Enhanced GravityZone Email Security Protection in 2025 

Bitdefender recently acquired Mesh Security which strengthens the GravityZone platform by adding native, dual‑layer email protection—first via an edge secure email gateway (SEG), and second through mailbox‑level API-based detection inside Microsoft 365 and Google Workspace environments.

For GravityZone users, this means their extended detection and response (XDR) and managed detection and response (MDR) tools now incorporate high‑fidelity email telemetry, significantly closing a longstanding visibility gap between endpoint, cloud, and inbox threat vectors.  

For MSP customers using GravityZone, the addition of Mesh’s MSP-native architecture brings powerful operational advantages. This includes a multi-tenant interface, policy templates, and integrations with PSA and RMM tools like ConnectWise and Kaseya to streamline deployment and management across multiple clients, reducing overhead and increasing efficiency.
