Credential-harvesting phishing
A pixel-perfect login page on a domain registered hours ago, with no attachment and no known-bad reputation to flag. The payload is the form itself, and the prize is a working password that will still work tomorrow.
Email security services: closing the channel most breaches start in
Email is the cheapest path to a stolen credential, which is why it is the first thing attackers try. We configure and manage advanced threat protection for Microsoft 365 and Google Workspace: reputation and authentication checks, real-time filtering, sandboxing and impersonation analysis, and the tenant hardening that stock defaults leave open.

The starting point
Why email is where the breach begins
One convincing message, one reused password, and an attacker is inside — past every perimeter control you paid for, holding a credential that works. Nothing about that requires a vulnerability, which is why filtering matters more than patching for this particular attack path.
It is also why email security and identity security are the same fight. Stop the phishing message and you stop the credential theft that our privileged access management controls and our managed SOC would otherwise have to catch further downstream, after the attacker is already authenticated and looking like a legitimate user.
Inspection
The four layers between an 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.
| Layer | What it checks |
|---|---|
| 1. Reputation and authentication | SPF, DKIM and DMARC records, and known-bad senders — checked before the message is accepted |
| 2. Real-time content filtering | Spam, malicious links and payloads, inspected at the gateway |
| 3. Advanced threat detection | Sandboxing, zero-day analysis and impersonation detection for what survives the first two |
| 4. Delivery | Clean mail reaches the inbox. Everything else is quarantined, logged and reportable. |
And when something still gets through — and something always does — a trained employee is the last layer. That is what security awareness training is for, and it is why we run the two together.
The gap
What default filtering keeps missing
These are the attacks built specifically to survive a stock Microsoft 365 tenant. None of them look like malware, which is the point.
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 before a scheduled run. Content filters see nothing wrong because technically nothing is wrong.
Zero-day payloads
Attachments and links exploiting flaws with no signature yet. Only behavioral analysis in a sandbox catches these before delivery, which is the layer most tenants never turn on.
Thread hijacking
An attacker inside a compromised mailbox replies within a real conversation, with real history above it. It passes every authentication check, because the sender genuinely is who they claim to be.
Links that arm later
A URL that is clean on delivery and weaponized an hour after it lands. Scanning at the gate is not enough; links need checking at the moment somebody clicks.
Quiet forwarding rules
After a takeover, an inbox rule silently copies mail to an outside address. Nobody notices until money moves, which is why mailbox rule changes are watched as an identity event rather than an IT curiosity.
Scope
What we deliver
| Capability | What it covers |
|---|---|
| Advanced threat detection | Phishing, malware and zero-day attacks stopped before the inbox, not explained after a click |
| Real-time filtering | Spam, ransomware payloads and malicious links blocked without slowing legitimate mail to a crawl |
| Microsoft 365 hardening | Your tenant configured beyond the defaults attackers count on — usually the single highest-impact change available in a week |
| Data protection | Controls that prevent data loss over email and keep communications aligned to the standards you report against |
| Email continuity | Message flow maintained during outages, so a platform disruption does not become a business one |
| Mailbox rule monitoring | Forwarding and rule changes watched as an account-takeover signal, feeding the same alert queue as the rest of your identity events |
Why Applied IAM
Why an identity firm runs email security
Because the two problems are one problem. Almost every credential-theft chain starts with a message and ends with an account. The team that hardens your tenant, the team that watches for the takeover, and the team that controls what the stolen account can reach should not be three different companies, each seeing a third of the picture and none of them responsible for the middle.
Where an incident does happen, the same people who see the alert can close the access path. That is the argument, and it is the only one that matters.
FAQs
Common questions about email security
The built-in filtering catches the obvious. What it misses is what is engineered to pass it: a login page on a brand-new domain, a payment-change request with no link in it, a reply inside a real thread. Tenant hardening and a layer above the defaults is usually the highest-impact change an organization can make in a week.
We configure and manage it. Recommending a product and leaving you to deploy it is how tenants end up half-configured — which is worse than the default, because everyone assumes it is handled.
No. Protection is added on top of what you already run. No migration, no mailbox move, no change to how people send mail.
Filtering is one layer: spam, known-bad senders and obvious payloads. Email security is the whole stack around it — authentication records configured properly, sandboxing, impersonation detection, click-time link checking, tenant hardening, and monitoring for what happens after a compromise.
Two things. The person who received it reports it, which is what security awareness training is for. And the account that might have been compromised gets watched, which is what the managed SOC does. No filter reaches 100%, so the layers after it matter as much as the filter itself.
Yes. Authentication records, retention, data loss prevention and logging all appear on SOC 2, HIPAA and cyber-insurance questionnaires. Configuring them properly and evidencing them is part of a compliance readiness assessment.
