Microsoft 365 security

Your business lives in Microsoft 365. So do the attackers.

Email, files, identities, logins - it's all in one place, which is exactly why it's the number-one target. Seclyn watches your Microsoft 365 environment for the sign-ins, mailbox tricks, and account takeovers that lead to real breaches, and shut them down early.

WHAT YOU GET
✓ Identity & sign-in protection
✓ Email & phishing threat monitoring
✓ Detection of risky mailbox & sharing rules
✓ Response that locks out compromised accounts
✓ Protection for the data your business runs on
Attackers don't break into Microsoft 365. They log in.
Why this matters

One stolen password can give away your entire business.

Your email is your identity

Email is tied to approvals, password resets, vendors, customers, and critical business processes. Control it, and you control the business.

One account opens many doors

Microsoft 365 connects email, Teams, SharePoint, OneDrive, customer data, and cloud apps through a single identity.

Most attacks look normal

Successful sign-ins, mailbox rules, and file downloads all look legitimate - until someone connects the dots.

What we're actually looking for

Your employees may sign-off at 5PM, but hackers don't.

Seclyn Security Platform

Microsoft shows signals. Seclyn Security Platform connects them.

Microsoft 365 flags events one at a time. Seclyn Security Platform ties them together into a single story - so we catch the takeover, not just the login.

Suspicious login → Mailbox rule created → Large file download → Seclyn Security Platform: account contained

2:46 PM
Session revoked, rule removed, password reset

Questions worth asking

✓ Would you know if someone was accessing your Microsoft 365 environment right now?
✓ Who investigates suspicious sign-ins and mailbox activity?
✓ What happens if an employee account is compromised?
✓ Are Microsoft alerts actively reviewed - or simply generated?
✓ Who responds when something needs immediate action?

Most businesses already have Microsoft 365. Far fewer have someone actively watching, investigating, and responding.
