What is GravityZone Extended Email Security?
Bitdefender’s NEW email-security product (launched April 2026) — a secure email gateway PLUS API-based behavioural protection (CAPES/ICES), against phishing, BEC, malware and spam, unified with endpoint in one GravityZone console.
Siloed email + endpoint (& gateway-vs-API) vs Bitdefender — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Unprotected / signature email | GravityZone Extended Email Security (Bitdefender) |
|---|---|---|
| Email + endpoint | Two vendors, two consoles | One GravityZone platform |
| Coverage | Gateway OR API | Gateway AND API, one product |
| BEC / account takeover | Missed by signatures | Behavioural (post-delivery API) |
| Remediation | Manual mailbox hunt | Automated claw-back, all mailboxes |
| Detection engine | Varies | Bitdefender-grade (top-efficacy) |
| Cost | Premium email brand | Efficacy at value |
| Correlation | Email & endpoint siloed | One incident, seen whole |
| Best fit | (varies) | Email unified with endpoint, at value |
Bitdefender GravityZone Extended Email Security is a NEW (Apr 2026) email-security product — a secure email gateway PLUS API-based behavioural protection (CAPES/ICES) against phishing, BEC, malware and spam, unified with endpoint on one GravityZone platform, built on the Mesh engine (acquired 2025). Honest: it’s newer/narrower than the leaders — Proofpoint has the broadest platform, Abnormal is the AI-native ICES challenger (TechBag sells both), Defender O365 wins on M365 E5. Its edge is unification + value. TechBag scopes it, compares honestly & adds GST.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Two Layers, One Product
Two layers in one product: a secure email gateway filters mail inline before delivery, and API protection (CAPES) on Microsoft 365 / Google Workspace catches BEC after it.
Unified with Endpoint (GravityZone)
Email lives in the same GravityZone console as Bitdefender endpoint protection, so a malicious email and the endpoint it lands on are correlated, not siloed.
Behavioural, ICES-Style Detection
The API layer analyses behaviour, identity and content signals to spot malware-free attacks — BEC, impersonation, account takeover — that slip past signature filters.
Built on Mesh, Bitdefender-grade
Built on Mesh Security, the email specialist Bitdefender acquired in 2025 (Mesh is still sold standalone, MSP-focused), fused with Bitdefender’s detection heritage.
Filter, Detect, Remediate
It filters bad mail at the edge, detects socially engineered threats behaviourally after delivery, and claws back delivered messages across mailboxes when a verdict changes.
Telemetry from endpoint, network and cloud woven together — one correlation pass, no chasing alerts between consoles.
Twelve capabilities. Filter, detect, remediate.
Bitdefender protects email at the gateway AND through the API — unified with the endpoint you already protect — the newest email-security product from the Bitdefender portfolio.
Anti-Spam & Bulk Filtering
High-accuracy spam and graymail filtering at the gateway stops the obvious noise before it lands, keeping inboxes clean.
Malware & Attachment Scanning
Scans attachments with Bitdefender’s top-ranked engine, blocking known and novel malware at the gateway before delivery.
URL Protection & Sandboxing
Time-of-click URL checks and attachment sandboxing deliver a verdict before users are exposed to weaponised links or files.
Secure Email Gateway (Inline)
The inline gateway stops spam, malware and malicious content before the inbox, complementing the post-delivery API layer.
Advanced Phishing Detection
Content and behavioural analysis detects credential-harvesting pages, lookalike domains and brand impersonation.
Business Email Compromise (BEC)
Spots business email compromise and impersonation — fake CEO, vendor or invoice fraud with no malware — by analysing identity, tone and intent.
Account Takeover Detection
The API layer sees inside the mailbox, flagging anomalous sends, suspicious logins and internal phishing from a hijacked account.
API-Based Behavioural Analysis (CAPES)
Connects to Microsoft 365 / Google Workspace by API for post-delivery analysis, catching social engineering the gateway can’t.
Automated Message Remediation
When a verdict changes, delivered malicious messages are clawed back from every affected mailbox automatically.
Unified with Endpoint (GravityZone)
Email and endpoint in one GravityZone console, so an email threat and the endpoint it lands on are seen as one incident.
Reporting & Threat Visibility
Dashboards show what was blocked, clawed back and why, from the same console lean teams use for endpoint.
MSP-Ready (Mesh Lineage)
Built on Mesh, still sold standalone to MSPs, the engine suits multi-tenant delivery alongside Bitdefender’s MSP endpoint.

Here’s what genuinely sets Bitdefender apart (and where a rival leads).
Unified with endpoint — email and the endpoint it lands on, seen together
Extended Email Security lives in the same GravityZone console as Bitdefender endpoint, so a phishing email, the click and what happened on the machine form one incident, not two fragments. That helps lean teams, common in India. Honest: it is a new product (April 2026); the draw is unification, not leader-level breadth.
API AND gateway in one — pre-delivery and post-delivery together
Email security has split into the inline gateway, strong on spam and malware, and API-based ICES, strong on post-delivery BEC and phishing. Extended Email Security does both: the gateway filters at the edge, the API layer watches Microsoft 365 / Google Workspace and claws back messages when a verdict changes.
Top-efficacy detection at value — Bitdefender-grade, applied to email
It applies Bitdefender’s top-ranked detection engine — one other vendors OEM — to email, fused with the Mesh engine, at a price below premium brands like Proofpoint and Abnormal. Honest scope: it is newer and narrower than Proofpoint; the case is efficacy at value and one console with Bitdefender endpoint.
Built on Mesh — a focused email engine, backed by a proven vendor
Rather than build from zero, Bitdefender acquired Mesh, an MSP-focused email specialist still sold standalone, in 2025 and made its engine the core, backed by labs and threat intelligence from a vendor protecting 500M+ systems. Honest note: the unified product only launched April 2026, early against decade-plus incumbents.
Email is the #1 attack vector — and India feels it acutely; TechBag makes it local
Email is the #1 attack vector, and lean, fast-digitising Indian organisations are heavily targeted by BEC and credential phishing. Bitdefender pairs gateway filtering with API behavioural detection, unified with endpoint, at value. It lists in USD, so TechBag scopes the fit honestly and adds INR/GST and support.
The honest scope
A new product (April 2026, built on Mesh) unifying a gateway and API protection with endpoint in GravityZone. Rivals lead elsewhere: Proofpoint on platform breadth (DLP, archiving, training), Abnormal AI on AI-native BEC detection, Defender for Office 365 on E5 economics. TechBag compares all honestly.

Quick poll — what’s driving your evaluation?
Talk to an advisor“We already ran Bitdefender on endpoints, so we added email in the same console. A phishing email and its machine are one incident.”
“Gateway and API in one product — we filter malware at the edge and catch BEC and account takeover inside the inbox.”
“TechBag told us Proofpoint has the broader platform. For us, unified-with-endpoint at value mattered more than breadth.”
“It launched in 2026, so it’s narrower than the incumbents, but it’s built on the Mesh engine. Credible, and the price is right.”
“Remediation clawed back a malicious email from every mailbox that got it, automatically — no manual hunt.”
“For our budget, gateway plus behavioural API from a top-efficacy vendor at value made sense. In India, that matters.”
“As an MSP the Mesh lineage suits us — multi-tenant email, and it pairs with Bitdefender endpoint on one platform. One relationship for both.”
“TechBag compared it honestly with their own Proofpoint and Abnormal lines, and added INR/GST and local support.”

Bitdefender vs the email-security field
Proofpoint, Abnormal AI, Microsoft Defender for Office 365, Mimecast and Barracuda — honest lanes; Bitdefender is a NEWER, narrower entrant whose edge is being unified with endpoint + top-efficacy engine + API+gateway in one + value. Broadest platform? Proofpoint (we sell it). Pure-play AI ICES? Abnormal (we sell it). On M365 E5? Defender O365. We say so.
| Dimension | Bitdefender | Proofpoint | Abnormal AI | MS Defender O365 | Mimecast | Barracuda |
|---|---|---|---|---|---|---|
| Position | Unified w/ endpoint; API + gateway (new) | Email-security MQ Leader, broadest | AI-native behavioural ICES | Bundled with M365 E5 | Established gateway + continuity | Established gateway (SMB-strong) |
| Platform breadth (DLP/archive/awareness) | Narrower (newer entrant) | Broadest (DLP, archiving, awareness) | Focused on ICES | Via MS stack | Broad (+ continuity/archiving) | Solid |
| API-based behavioural (ICES) detection | Yes (CAPES, post-delivery) | Yes (adaptive email security) | Yes (purpose-built, AI-native) | Some (Defender O365) | Adding | Adding |
| Secure email gateway (SEG, inline) | Yes (unified with API) | Yes (mature) | API-only (no gateway) | Yes (EOP + Defender O365) | Yes (mature) | Yes (mature) |
| Unified with endpoint (one platform) | Yes — GravityZone (the edge) | Email-focused (separate) | Email-focused (separate) | Yes (MS Defender stack) | Email-focused | Some (broader Barracuda) |
| Detection efficacy (engine) | Bitdefender-grade (OEM’d) | Strong | Strong (AI) | Good (MS-centric) | Good | Good |
| Value / cost | Efficacy at value | Premium | Premium | 'Free' if on E5 | Mid | Competitive (SMB) |
| Best fit | Email unified with endpoint, at value (new) | Broadest email platform (DLP/archive/awareness) | Pure-play AI-native behavioural ICES | Already on M365 E5 | Gateway + continuity/archiving | SMB gateway at value |
Which approach fits you?
Honest fit signals — because the fastest way to lose your trust is to pretend one product wins every scenario.
