Where Incidents Actually Start

The incidents that reach most organizations are rarely exotic. A password is guessed across thousands of rotating addresses. A shared mailbox is still on basic authentication. A domain with DMARC left in monitoring mode lets a spoofed invoice land in the inbox. One account without a second factor becomes the way in. Security operations means closing those doors one at a time, and watching to make sure they stay closed.

What We Do

Practical security for the way your organization actually works, rolled out without locking anyone out.

Identity Enforcement

MFA and Conditional Access rolled out in waves, each account checked for a usable factor first
Passkeys and authenticator apps as standard, with SMS, email codes and legacy authentication removed
Password-spray exposure found and shut: basic authentication disabled, app passwords revoked
Privileged and break-glass accounts kept separate and protected

Email Authentication

SPF, DKIM and DMARC published correctly for every domain, plus MTA-STS and TLS reporting
DMARC taken to quarantine and then reject based on real reporting, so legitimate mail keeps flowing
Spoofing of your domain detected, traced and shut down
Phishing that impersonates your own staff analyzed and blocked

Endpoints

Endpoint detection and response through Microsoft Defender for Business, with a managed review layer
Daily posture checks: patch state, end-of-life systems, unexpected remote-access tools, local admin changes
Workstation hardening applied consistently
Device compliance reported monthly

Incident Response

Credential-spray attacks traced from the firewall, not guessed at
Compromised accounts contained fast: sign-in blocked, sessions revoked, malicious rules removed, forwarding checked
Business email compromise worked through containment and evidence collection
The paperwork your insurer and bank will ask for, in plain language

Firewall and Network

Firewall and VPN configuration reviewed and tightened
Remote access moved to modern authentication
Firmware and known vulnerabilities tracked
Vendor security records checked before you buy

People

Security awareness and phishing simulation through Microsoft Attack Simulation Training
Clear guidance for staff before anything changes for them
Reported phishing routed to someone who will actually look at it

Reported Monthly

Identity, endpoint, email and backup posture arrive in one plain-English report on the first of the month through Argos Security Assurance. Something you can hand to leadership, an auditor or your cyber insurer.
