Email & Account Security
Email is the #1 attack vector for small businesses. We layer advanced threat protection over Microsoft 365 or Google Workspace and watch your accounts 24/7 — so phishing, BEC, and account takeovers stop before they hurt the business.
Why Email Security Is the First Battle
Industry estimates suggest that more than 90% of cyberattacks begin with an email. Verizon's annual Data Breach Investigations Report consistently puts phishing and pretexting among the top causes of breaches affecting SMBs, and the FBI's IC3 records business email compromise as the single costliest cyber crime category — exceeding $50 billion in reported losses globally over the last decade.
The reason is structural: email is a trusted protocol designed in the 1980s for a world without attackers. Modern threat actors exploit that trust with spear phishing, lookalike domains, vendor impersonation, and credential harvesting pages that look identical to your Microsoft sign-in screen.
Native Microsoft 365 and Google Workspace controls catch generic bulk spam well — but they were never designed to be a primary defence against targeted attacks. That's where a managed email security service layers in.

What's Included
Fully managed — we deploy, operate, monitor, and respond.
How It Works
Five steps, mostly invisible to your team once deployed.
Deploy
We connect to your Microsoft 365 or Google Workspace tenant and configure the advanced threat protection layer with tuned policies for your business.
Enforce
MFA gets turned on for every user. Conditional access policies block high-risk sign-ins. External-mail banners alert users to inbound mail from outside the company.
Monitor
Our SOC watches every login, every flagged message, every suspicious mailbox rule — 24/7. Anomalies trigger investigation, not just an email to you.
Respond
When an account shows signs of compromise, we contain it: revoke sessions, force reset, audit mailbox rules, check for exfiltration. You get notified, not woken up.
Report
Monthly summary in plain English: threats blocked, top attack patterns, account events handled, recommendations for the team.
Native vs Managed Email Security
How our managed service compares to the default Microsoft 365 / Google Workspace controls.
| Dimension | Native Only | Kapacyber Managed |
|---|---|---|
| Inbound threat filtering | Basic spam + known-bad | Advanced incl. zero-day, impersonation, ATP |
| BEC defence | Minimal | Layered stack + process controls |
| MFA enforcement | Available, often not enforced | Enforced across all users |
| Account compromise monitoring | Logs available, no one watching | 24/7 SOC monitoring + response |
| Mailbox-rule auditing | Manual only | Automated, alerted |
| Response when account is compromised | You figure it out | Contained in under 15 minutes |
Tools We Operate
We choose tools based on fit for your stack — not on vendor incentives. Most engagements use one or more of:
Built For
- • 5–75 person businesses on M365 or Google Workspace
- • Companies that handle payment, financial, or personal data
- • Regulated industries (HIPAA, NAIC, FTC Safeguards, PCI)
- • Businesses that have been targeted by BEC or phishing
- • Cyber-insured businesses needing documented controls
Not Built For
- • Businesses on legacy on-premise mail servers (we'll help you migrate first)
- • Companies that prefer self-managed security tooling

Frequently Asked Questions
Isn't Microsoft 365 / Google Workspace email security already enough?
The built-in filters catch generic bulk spam well but miss targeted attacks — spear phishing, business email compromise (BEC), invoice fraud, and zero-day malicious attachments. Our managed email security layers advanced threat protection on top, plus active monitoring and response.
Will this slow down or block legitimate emails?
False-positive rates on modern email security are below 0.1% when properly tuned. We monitor quarantine, release legitimate mail quickly, and tune filters monthly. You won't lose customer emails — we make sure of it.
How fast can you respond if my account is compromised?
Account compromise events are P1 in our SOC — typical response time is under 15 minutes. We immediately revoke active sessions, force a password reset, audit the mailbox for forwarding rules, and check for data exfiltration.
Do you cover both Microsoft 365 and Google Workspace?
Yes. We deploy and manage on both platforms. The control set is similar across the two; the tools differ.
What's BEC and how do you defend against it?
Business Email Compromise is when an attacker uses email to impersonate a vendor, executive, or partner and trick someone into wiring money or sharing data. We defend with a layered stack: advanced filters, impersonation detection, banner warnings on external mail, MFA, conditional access, and process controls. See our full BEC guide for the detail.
