Services — Email Security

Close the #1 way attackers get in.

Advanced threat protection for Microsoft 365 and Google Workspace — stopping the phishing, malware, and account-takeover attempts that start most breaches, before they reach an inbox.

Why it matters

Email is where the breach begins

Email is the number-one attack vector for cyber criminals, and the reason is simple: it's the cheapest path to a stolen credential. One convincing message, one reused password, and an attacker is inside — past every perimeter control you paid for.

That's why email security and identity security are the same fight. Stop the phishing email and you stop the credential theft that our privileged access management and threat detection would otherwise have to catch downstream.

How mail gets filtered

Four layers between the attacker and your inbox

Every message is inspected in sequence. Most threats die at the first layer — the ones engineered to survive it are exactly why the layers underneath exist.

Legitimate mailPhishingMalwareRansomwareSpoofed sender

Layer 1

Reputation & authentication — SPF, DKIM, DMARC, known-bad senders

Layer 2

Real-time content filtering — spam, malicious links, payloads

Layer 3

Advanced threat detection — sandboxing, zero-day and impersonation analysis

Clean mail reaches the inboxEverything else is quarantined, logged, and reportable

And when something still gets through, a trained employee is the last layer — which is why we run both.

What we do

Layered protection for the modern inbox

Detection

Advanced threat detection

Stop phishing, malware, and zero-day attacks before they reach the inbox — not after someone's already clicked.

Filtering

Real-time filtering

Spam, ransomware payloads, and malicious links blocked in real time — without slowing legitimate mail down.

M365

Microsoft 365 hardening

Your tenant configured beyond the defaults attackers count on — the single highest-impact change for most organizations.

Data

Data protection & compliance

Controls that prevent data loss over email and keep communications aligned to the standards you report against.

Continuity

Email continuity

Access and message flow maintained even during outages, so a platform disruption doesn't become a business one.

Integration

Seamless integration

Compatible with Microsoft 365, Google Workspace, and most major platforms — no migration required to add protection.

The threats

What default filtering keeps missing

These are the attacks built specifically to survive a stock Microsoft 365 tenant.

Credential-harvesting phishing

A pixel-perfect login page on a domain registered hours ago, with no malicious attachment and no known-bad reputation to flag. The payload is the form — and the prize is a working password.

Business email compromise

No link, no attachment, no malware — just a plausible message from a compromised or lookalike account asking finance to change payment details. Content filters see nothing wrong because technically nothing is.

Zero-day payloads

Attachments and links exploiting flaws with no signature yet. Only behavioural analysis in a sandbox catches these before delivery.

Thread hijacking

An attacker in a compromised mailbox replies inside a real, existing conversation. It passes every authentication check because the sender genuinely is who they claim.

Malicious links that arm later

A URL that is clean on delivery and weaponised after it lands. Scanning at the gate isn't enough — links need checking at the moment of click.

Quiet forwarding rules

After a takeover, attackers add an inbox rule that silently copies mail out. Nobody notices until money moves — which is why we monitor rule changes, not just messages.

How we deliver

From audit to running protection

Audit

We review your current tenant configuration and show you exactly what can still land in an inbox today.

Harden

Authentication records, anti-phishing and anti-spoofing policies, and safe-link handling configured past the defaults.

Layer

Advanced threat protection deployed in front of the mailbox, with sandboxing and impersonation analysis.

Tune & support

Filtering calibrated to your real mail patterns so legitimate email lands — then ongoing support and reporting.

Why us

Why teams choose AppliedIAM for email security

We configure and run it

Not a product recommendation — hands-on hardening, deployment, tuning, and ongoing support from certified engineers.

Identity-aware by default

We treat the inbox as the front door to every identity, so protection is aimed at the credential theft that actually causes breaches.

Pairs with awareness training

Technology stops most of it; people catch the rest. Email security and security awareness training work as one program.

Tuned to cut false positives

Filtering calibrated to your mail patterns, so protection doesn't come at the cost of legitimate email landing in junk.

Fits what you already run

M365, Google Workspace, or a mix — we add a layer, we don't force a rip-and-replace.

Part of a whole program

One partner for email, identity, monitoring, and compliance — not a point tool bolted on in isolation.

FAQ

Common questions about email security

Isn't Microsoft 365 already secure enough?

Microsoft 365 has real built-in protection, but it's tuned to a broad baseline and attackers test against those defaults constantly. Advanced phishing, business email compromise, and zero-day payloads routinely slip past out-of-the-box settings. We harden the configuration, add a layer of advanced threat detection, and tune it to your organization — closing the gap between “default on” and “actually protected.”

What email platforms do you support?

Primarily Microsoft 365, where we do the deepest hardening, and Google Workspace. The advanced threat protection layer is compatible with both, plus most major mail platforms, so it fits whatever you already run rather than forcing a migration.

Why is email security an identity security firm's business?

Because email is how credentials get stolen. The overwhelming majority of breaches start with a phishing email that harvests a login — and that login is exactly what our privileged access and governance work protects. Securing the inbox is securing the front door to every identity behind it.

Do you handle the setup, or just recommend tools?

We configure and run it. That means hardening your Microsoft 365 tenant, deploying the threat-protection layer, tuning the filtering to cut false positives, and staying on for support — not handing you a product and a login.

What about email that arrives during an outage?

Email continuity keeps messages flowing even when your primary mail service has a disruption, so communication doesn't stop when the platform hiccups — and nothing is lost in the gap.
