Bitdefender has
announced plans to acquire Mesh Security, a move aimed at integrating advanced email protection into its GravityZone platform and enhancing its
managed detection and response (MDR) and
extended detection and response (XDR) offerings. The acquisition reflects Bitdefender’s broader strategy to unify security signals across key attack vectors, email, endpoint, network, identity, and cloud, and provide deeper visibility and faster response for enterprise and MSP partners.
Email continues to be a top attack vector for ransomware, phishing, and business email compromise. Mesh’s dual-layered email protection, combining a secure email gateway (SEG) with mailbox-level defense via API, adds visibility and control across the full lifecycle of email threats, both pre- and post-delivery. According to
Andrei Florescu, President and General Manager of Bitdefender Business Solutions Group, this design directly strengthens the company’s XDR and MDR capabilities.
“Mesh strengthens Bitdefender’s GravityZone XDR and MDR by combining perimeter-based protection via a secure email gateway (SEG) with mailbox-level defense using an API-based deployment model. This dual-layered approach ensures both pre-delivery and post-delivery threats are detected, blocked, and correlated across the entire attack surface. It enhances detection of evasive threats like BEC, account compromise, and lateral phishing. Its deep telemetry will feed directly into GravityZone XDR, allowing customers and the Bitdefender MDR team to detect email-borne threats earlier, correlate them with endpoint, identity, and network signals, accelerating incident response and uncovering multi-stage attack campaigns that would otherwise remain hidden in silos.”
Bitdefender is also rethinking the role of email telemetry in broader threat detection and correlation. While many XDR platforms treat email as a silo, Mesh’s integration ensures it becomes a primary telemetry source.
“By integrating Mesh into GravityZone, Bitdefender treats email as a first-class telemetry source, not a separate layer. The combination of SEG and mailbox-level inspection gives us a complete picture of how email threats evolve post-delivery, including lateral movement and user interaction. This enriched data will be fed into our central correlation engine alongside endpoint, network, identity, and cloud signals. As a result, threats that span vectors, like phishing-to-malware or business email compromise leading to privilege escalation, can be detected and neutralized faster, with stronger context and correlation than siloed email solutions can provide.”
Mesh’s platform is also optimized for MSPs and MSSPs and co-managed detection environments. Its API-based design and centralized management features allow for shared visibility, consistent policy enforcement, and collaborative remediation between MSSPs and internal security teams.
“Mesh is designed for modern, co-managed environments. For co-managed environments, this means MSSPs and customer teams can access the same high-fidelity email telemetry, apply shared policies, and coordinate response actions from a single console. This accelerates remediation, simplifies operations, and strengthens collaboration, all without bolting on a separate product or siloed workflow.”
With this acquisition, Bitdefender continues to align its platform with how modern security operations teams work, integrated, collaborative, and built for scale across vectors. The addition of Mesh not only deepens email threat protection but enhances Bitdefender’s ability to deliver end-to-end coverage that works for enterprises and MSPs alike.
