Phishing, BEC, malware — stopped before the inbox.
Cloudflare Email Security, deployed and operated by Zentara — in front of your existing mail server.
Email remains the first hop of most intrusions. Licenses alone don't stop it — tuning and response do. Zentara owns the layer between the internet and your people: designed, deployed, tuned against live campaigns, and reported every month.

The problem
Email is still the first hop.
Most intrusions don't start with an exploit — they start with a message. Provider built-in filters catch the generic bulk; the targeted remainder lands exactly where it was aimed: in front of a person with a deadline.
The productivity tax
When half of inbound mail is junk or worse, triage becomes everyone's part-time job — and the filter of last resort is a tired employee at 5 pm.
The expensive click
Phishing and BEC don't need malware to cost money — a convincing invoice and a lookalike domain are enough to move a transfer to the wrong account.
Zero visibility
Without centralized inspection, a campaign against your staff is discovered by its consequences — never by its first attempt.
Share of inbound mail that was spam, phishing, or malicious
Observed at a mid-size client, prior to deployment · Prepared for:
In six months, threats grew from under a third of inbound mail to nearly half. At that point the real spam filter is your staff — the layer most likely to fail.
Architecture
In front. Not instead.
The filtering layer is added ahead of the mail server you already run — via MX redirection or API connector. No mailbox migration, no provider change, no user disruption.
Origin
The internet
Every sender — customers, partners, and the campaigns pretending to be both.
The layer Zentara runs
Cloudflare Email Security
Every message inspected before delivery — sender reputation, link and attachment analysis, impersonation detection, global campaign intelligence. Threats are quarantined; clean mail passes untouched.
Unchanged
Your mail server
Microsoft 365, Google Workspace, or on-premises — mailboxes, users, and workflows exactly as they are.
Deployment preserves delivery throughout — cutover is scheduled, tested, and reversible.
Deploy & run
Licenses don't stop phishing. Operations do.
Two phases, one accountable team: a three-to-four-week deployment, then a standing operation that keeps detection tuned to what attackers try next.
Phase one · Weeks 1–4
We deploy
Scoping & design
Domain, mailbox, and mail-flow inventory; integration mode chosen — MX inline or API.
Integration & policy
Cloudflare Email Security connected in front of the existing flow; SPF, DKIM, DMARC set correctly; detection and quarantine policies configured.
Testing & tuning
Detection validated against live traffic; initial tuning to push false positives down before anyone notices the change.
Go-live & handover
Scheduled production cutover with delivery preserved; documented configuration; admin briefing; operations handed to the Zentara maintenance team.
Phase two · Standing
We run
Continuous tuning
Detection policies reviewed against live campaign data and adjusted as attacker patterns shift — not set once and forgotten.
Quarantine management
Quarantined mail reviewed, false positives and negatives handled, legitimate messages released — through a ticketed queue with a named team.
Monthly reporting
Executive summary plus the technical report: volumes blocked by category, campaign trends, targeted roles, and recommendations.
Quarterly reviews
A standing session to evaluate effectiveness, revisit policies, and adjust for what the business changed that quarter.
Four weeks to a filtered inbox
Your users notice nothing. Except the quiet.
Scoping to go-live in three to four weeks, delivery preserved throughout — then a named team tuning, managing quarantine, and reporting every month.
What you see
A report your CFO can read.
Every month: what was blocked, who was targeted, what changed — in executive language on page one and technical detail behind it.

Technical detail behind it
Campaign patterns, targeted roles, authentication posture, and quarantine dispositions — for the team that acts on it.
Trend, not snapshot
Month-over-month movement against your baseline — proof the layer is working, in numbers.
Blocked quietly. Reported loudly.
Build the program
Pairs well with
Managed SOC
Where the SOC is subscribed, quarantine events escalate into a watched queue — email stops being a silo and becomes telemetry.
Threat Hunting
Email is initial access. Hunts chase what a click may have started — before it becomes an incident report.
Incident Response & Digital Forensics
If the click already happened, response takes over — containment, forensics, and the evidence discipline that survives scrutiny.

Microsoft 365, Google Workspace, or on-premises — your server, your mailboxes, and your users stay exactly where they are. Mail simply arrives filtered.
