What is Coro Email Security?
Anti-phishing, anti-malware & BEC protection with inbound gating and outbound encryption — API-connected to M365/Google, managed in the Actionboard with AI auto-remediation. Solid, affordable email, bundled into one platform.
A separate email tool vs Coro’s bundled email — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Unprotected / signature email | Email Security (Coro) |
|---|---|---|
| Email tool | A separate vendor/console | One module of Coro |
| Deployment | MX change (gateway) | API-connected, no re-route |
| Remediation | Manual clawback | AI auto-remediation |
| Encryption | Another tool | Bundled outbound encryption |
| Billing | Separate contract | One flat per-user price |
| For lean IT | Another console | The same Actionboard |
| BEC depth | (varies) | Solid (not best-of-breed ICES) |
| Best fit | (varies) | SMB email inside one consolidated platform |
Coro Email Security delivers anti-phishing, anti-malware and BEC protection with inbound gating and outbound encryption, API-connected to M365/Google, managed in the Actionboard with AI auto-remediation — solid, affordable email inside one consolidated platform for SMBs. Honest: it’s not a best-of-breed ICES — Abnormal and Harmony use deeper behavioural AI on BEC (TechBag sells Abnormal). TechBag scopes it & 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.
API-Connected to M365 / Google
Coro Email Security connects via API to Microsoft 365 or Google Workspace — so it protects the inbox without changing your MX records or re-routing your mail. Connect and protect. No mail-flow surgery.
Inbound Gating
Filter inbound mail for phishing, malware and spam — gating the mass of attacks before they reach users. Stop the flood at the front door. The first, biggest win.
BEC & Phishing Detection
Detect business email compromise, impersonation and advanced phishing — the socially-engineered attacks that cost the most — flagging what basic filters miss. Catch the con. Beyond simple spam filtering.
Auto-Remediation (clawback)
When a malicious message is caught (even post-delivery), Coro auto-remediates — clawing it back from inboxes — so a lean team doesn’t chase it manually. Catch it, then remove it. Automated cleanup.
Managed in the Actionboard
Email alerts and actions live in the Actionboard — the same console as endpoint, cloud/DLP and network — so email security is one module of one platform, at one flat per-user price. One console, one bill. Consolidation is the value.
One agent on every machine, one console over all of them — modules attach without a second operational world.
Twelve capabilities. Filter, detect, remediate.
Coro stops the mass of email attacks and claws back what slips through — API-connected, one console — the email module of portfolio, and paired with the human firewall.
Anti-Phishing
Filter phishing and credential-lure emails — the most common way attackers get in — gating them before they reach users. Stop the click. The top attack vector, filtered.
Anti-Malware & Attachments
Scan attachments and links for malware — blocking malicious payloads and drive-by links before they land. No malicious attachment gets through. The payload, blocked.
Spam & Bulk Filtering
Filter spam and bulk mail so the inbox stays usable and the real threats are easier to see. Cut the noise. A cleaner inbox for busy teams.
Inbound Gating (M365/Google)
API-connected to Microsoft 365 or Google Workspace, Coro gates inbound mail — no MX change, no re-routing — stopping the mass of attacks at the door. Protect the inbox, keep your mail flow. Frictionless.
Business Email Compromise (BEC)
Detect BEC — fake invoices, CEO fraud, wire-transfer requests — the payload-less social engineering that causes the biggest losses. Catch the costliest attack. Solid SMB-grade BEC defence.
Impersonation & Spoofing
Catch executive and brand impersonation and spoofing — flagging a fake ‘CEO’ or spoofed partner before a user acts on it. Know the real from the fake. Impersonation, caught.
Advanced & Targeted Phishing
Detect the polished, targeted phishing lures that get past basic reputation filters — by looking at content and intent, not just known-bad indicators. Catch the clever phish. Beyond reputation lists.
Post-Delivery Clawback
Catch a malicious message even after it lands and auto-remediate it — pulling it from inboxes org-wide — so an SMB team doesn’t chase it by hand. Remove it after delivery. Automated cleanup.
AI Auto-Remediation
Coro AI auto-remediates routine email threats automatically — handling the noise so a lean IT team isn’t buried in triage. Good-enough automation, by design. The lean-team superpower.
Outbound Email Encryption
Encrypt outbound email so sensitive messages stay protected in transit — helping meet data-protection obligations without a separate encryption tool. Protect what you send. Encryption, bundled.
Outbound Email Controls (DLP-lite)
Apply pragmatic outbound controls to catch sensitive data (PII) leaving via email — SMB-grade, coordinated with Coro’s cloud & data governance module. Watch what leaves. Right-sized data control.
Part of One Consolidated Platform
Email is one module of Coro’s platform — the same agent and Actionboard also run endpoint, cloud/DLP and network. Add modules on demand, one flat per-user bill. One console, all the coverage. The whole pitch.

Here’s what genuinely sets Coro Email apart (and where it’s solid, not best-of-breed).
Solid, affordable email protection — bundled into one platform
The single biggest reason SMBs choose Coro for email is that solid, affordable email protection comes BUNDLED into the same one-agent, one-console platform — not as yet another standalone tool with its own contract and console. The problem it solves: email is the #1 attack vector, so every SMB needs email security — but buying a dedicated email-security product means another vendor, another console and another bill on top of the sprawl a lean team already can’t manage. What Coro provides: anti-phishing, anti-malware and BEC protection, inbound gating and outbound encryption, API-connected to Microsoft 365 or Google Workspace — all managed in the Actionboard alongside endpoint, cloud/DLP and network, at one flat per-user price, with AI auto-remediation clawing back malicious mail. Why it matters: for a team that can’t staff security, getting real email protection WITHOUT adding another vendor or console — at an affordable, consolidated price — is exactly the value. Email is covered as one module of one platform. The value: Coro delivers solid, affordable email security bundled into one consolidated platform — one console, one bill. For lean SMB IT teams, that matters. TechBag scopes Coro’s email module for your mail environment. TechBag helps you cover the top attack vector, simply.
API-connected to M365/Google — deploy without re-routing mail
A practical strength of Coro Email Security is that it API-connects to Microsoft 365 or Google Workspace — so it deploys without changing your MX records or re-routing your mail. The problem it solves: a traditional secure email gateway requires changing MX records to route ALL mail through the vendor — a disruptive, risky, project-level change that a lean IT team dreads. What Coro provides: an API connection that sits with your native M365/Google mail — no MX change, no re-routing — gating inbound mail, detecting BEC and phishing, and auto-remediating (clawing back) malicious messages even post-delivery. Deployment is fast and low-risk. Why it matters: fast, frictionless deployment means an SMB gets email protection immediately, without a migration project or mail-flow risk — and because it’s API-based it can even remediate threats after they land. For teams that value simplicity, that architecture is a real advantage. The value: Coro Email Security API-connects to M365/Google — deploy without MX changes or mail re-routing, with post-delivery clawback. For fast, low-risk email protection, that matters. TechBag scopes the connection for your mail platform. TechBag helps you protect email without the project.
One console, AI auto-remediation — email security a lean team can run
A defining strength of Coro’s email is that it’s managed in ONE console (the Actionboard) with AI auto-remediation — so a lean IT team can actually run it without drowning in triage. The problem it solves: email security generates a lot of alerts and remediation work; without a SOC, an SMB team either ignores them or gets buried. What Coro provides: email alerts triaged and prioritised in the same Actionboard as every other module, with Coro AI auto-remediating routine threats automatically and clawing back malicious mail org-wide — so what’s left for the human is signal, not a flood. Why it matters: an SMB gets meaningful, ongoing email protection that a generalist can operate — the platform does the routine work, and the IT person handles exceptions, all in one place. It’s email security sized to the team that has to run it. The value: Coro’s email is managed in one console with AI auto-remediation — email security a lean team can actually run. For teams without a SOC, that matters. TechBag scopes and supports it. TechBag helps you run email security without a SOC.
Honest: solid & cheap, but not a best-of-breed ICES
A key part of choosing Coro for email is understanding what it is NOT: it’s solid and cheap, but it is NOT a best-of-breed ICES (Integrated Cloud Email Security). The honest truth: for the deepest BEC and social-engineering detection, dedicated behavioural-AI ICES tools go further. Abnormal AI and Check Point Harmony Email use deeper behavioural AI — modelling every identity and relationship to catch the most advanced, payload-less BEC — than Coro’s SMB-grade email module (TechBag sells Abnormal — see its hub). And dedicated platforms like Proofpoint Essentials go further on DLP, archiving and compliance. What Coro provides instead: strong, affordable, good-enough email protection as one module of a consolidated platform — which for most SMBs is exactly right, because they need broad, simple coverage more than category-leading BEC depth. Why it matters: knowing the trade lets you choose honestly — Coro for consolidated, affordable email inside one platform; Abnormal/Harmony when best-of-breed behavioural BEC detection is the priority. The value: Coro’s email is solid and cheap — but not a best-of-breed ICES; for the deepest BEC detection, Abnormal or Harmony (TechBag sells Abnormal). For an honest choice, that matters. TechBag compares them for you. TechBag helps you choose consolidated email or best-of-breed BEC.
Consolidated & affordable — and TechBag adds local India support
Coro’s email is part of a consolidated, affordable platform — and for Indian SMBs TechBag adds the local scoping, reselling and INR/GST support that make adopting it straightforward. Coro the company: founded in 2014 as Coronet (rebranded Coro ~2020), led by CEO Guy Moskowitz with co-founders Dror Liwer and Erez Nachmias, HQ Chicago with Tel Aviv R&D; it raised a $100M Series D in March 2024 led by One Peak at ~$750M valuation, remains private, and serves ~13,500 customers, with G2 awards for ‘Easiest to Use’ and ‘Best Support’. India relevance: BEC, phishing and invoice fraud are top threats for Indian SMBs, and because most run Microsoft 365 or Google Workspace, Coro’s API-connected email layers on cleanly. But there is NO confirmed Coro India office, entity or datacenter — India reach is 100% partner-led (e.g. a Climb Channel Solutions deal, Aug 2025), matching TechBag’s own model. Where TechBag adds value: Coro is quote-priced (historically ~US$8–10/user/month, directional only), so TechBag scopes the mail environment, compares honestly (vs Microsoft, Abnormal, Proofpoint), invoices in INR/GST, and helps confirm data-residency (no confirmed India region — verify before any claim). The value: Coro’s email is consolidated and affordable — and TechBag adds local scoping, honest comparison, INR/GST and support. TechBag supplies it with local support. TechBag provides Coro email, made local for India.
The honest scope
Coro Email Security is the email module of Coro’s consolidated SMB cybersecurity platform — anti-phishing, anti-malware and BEC protection, inbound gating and outbound encryption, API-connected to M365/Google and managed in the Actionboard with AI auto-remediation. From Coro (founded 2014 as Coronet; ~13,500 customers). The honest framing — strengths, and where it’s good-enough not best-of-breed: Coro’s email strengths are affordability, frictionless API deployment (no MX change), and being one module of a consolidated, easy-to-run platform. But the honest caveats matter: (1) It is NOT a best-of-breed ICES. Abnormal AI and Check Point Harmony Email use deeper behavioural AI on BEC — modelling identity and relationships to catch the most advanced payload-less attacks — than Coro’s SMB-grade email (TechBag sells Abnormal — see its hub). If best-in-class BEC detection is the priority, weigh those. (2) It’s narrower than a dedicated platform. Proofpoint (and its Essentials tier for SMB) goes further on DLP, archiving, compliance and awareness training; Coro’s email is a protection layer, not a full email-and-compliance platform. (3) SMB-scale limits: lighter reporting/log depth and a narrower integration surface than enterprise email-security platforms. So the honest positioning: for solid, affordable email protection bundled into one consolidated platform that a lean SMB team can run — API-connected, one console, one price — Coro is excellent; for best-of-breed behavioural BEC detection, Abnormal or Harmony; for a broad email-and-compliance platform, Proofpoint; if already on M365 E5, Defender for O365 is bundled. Many SMBs run Coro’s email precisely because consolidation and price beat category-leading depth for them. TechBag scopes Coro’s email honestly — comparing vs Abnormal, Proofpoint and Microsoft, and reselling and supporting it locally with GST.

Quick poll — what’s driving your evaluation?
Talk to an advisor“Email is our biggest exposure, and Coro gave us anti-phishing, malware and BEC protection from the same console as our endpoint and network security. One vendor, one bill — exactly what a two-person IT team needs.”
“It API-connected to our Microsoft 365 in minutes — no MX change, no re-routing. And Coro AI claws back malicious mail automatically, so we’re not manually pulling messages from inboxes.”
“Honest: we know Abnormal goes deeper on BEC with behavioural AI — TechBag told us so. But for our size, Coro’s solid, affordable email inside the one platform was the right call.”
“Outbound encryption bundled in meant we didn’t need a separate encryption tool for sensitive mail. For a small clinic, that consolidation is a big deal.”
“The phishing and spam filtering cleaned up the inbox immediately, and BEC/impersonation detection caught a fake-invoice attempt. Good-enough email protection at a price that made sense.”
“TechBag scoped our mailboxes, compared Coro honestly vs Abnormal and Microsoft, and invoiced in INR with GST. Consolidated email security, made local for us.”
“For an exporter, BEC and vendor-invoice fraud are a real risk — Coro’s BEC detection helped, though TechBag was clear Abnormal/Harmony go further if we ever need best-of-breed.”
“Coro is quote-priced now — TechBag scoped it, gave us a clear INR/GST number, and confirmed data-residency questions for us. Simple, affordable email as part of the whole platform.”
