HOW WE DEPLOY IT
Planned by default. Straightforward once it's live.
Proofpoint Essentials is a gateway, so mail routes through it before reaching your environment. That means the deployment is a mail flow change rather than an API connection, and it's planned rather than instant. We handle the cutover and stay with it until it's stable.
-
STEP 1
Scope and prepare
We confirm your domains, mail flow and existing filtering, and set the package and features to match your requirements. Nothing changes for your users at this stage.
-
STEP 2
Configure and test
We build the filtering policy, add your domains and users, and test mail flow through the platform before any live traffic moves. Existing rules that were compensating for your old filtering get reviewed at this point.
-
STEP 3
Cut over
MX records are updated to route mail through Proofpoint. We schedule this with you and monitor delivery closely through the change. Continuity means mail keeps flowing even if your environment is unavailable during the switch.
-
FOLLOWING DAYS
Tune and hand over
We review quarantine and delivery reports, adjust the policy, and set up digests and admin access. The engineer who configured it becomes your support contact.
Most deployments complete within a few days, depending on when you want the MX change scheduled.

FAQ
Frequently asked questions.
How long does deployment take?
Under 4 hours for an SMB on M365 Business Standard. Up to a week for mid-market with custom policies or DLP. We handle everything: DNS, policy build, user provisioning, tuning, and handover.
Can we trial before we commit?
Yes. We offer a 14-day free trial on any Proofpoint Essentials package. We set it up properly so the trial is meaningful, and at the end we show you what it caught and what it missed.
What’s the pricing model?
Per mailbox, per month. The figure depends on tier, seat count, contract length, and billing region. We send a written quote the same business day.
Do prices go up at renewal?
Proofpoint Essentials prices are typically stable at renewal unless your seat count changes or you move tiers. We will flag any changes in advance and advise on the best option for your budget.
Does it work with M365 Business Standard, or do we need E3?
Proofpoint Essentials works with all M365 plans including Business Standard. You do not need E3. Deployment uses an MX record change, which is plan-agnostic.
How does it compare to Microsoft Defender for Office 365?
Microsoft Defender catches commodity phishing. It misses BEC, supplier impersonation, lookalike domains, and lateral phishing. Proofpoint Essentials catches a measurable slice of what MDO P1 lets through, particularly around impostor threats and targeted attacks.
