Protect · Cyber Security

Most breaches aren't clever. They're gaps nobody checked.

Attackers go after the basics: unpatched software, weak sign-in controls, untested backups and staff who've never seen a convincing phishing email. We close those gaps first, then watch your environment around the clock — so if something gets through, it's caught and contained in minutes, not weeks.

FAQs

Cyber Security — frequently asked questions

What is MDR?

Managed detection and response means a team of analysts watches your devices, identities and logs 24/7 and acts on threats for you — not just alerts you about them.

We've been hit. Can you help now?

Yes. Contact our team immediately and our incident response process will contain the threat, investigate the scope and get you recovering.

Is Microsoft 365 secure out of the box?

No. Default settings leave important gaps. We configure it to CIS and Microsoft best practice and keep your Secure Score high with Cloud Shield 365.

Do you help with cyber insurance questionnaires?

Yes — we complete the technical sections with you and implement any controls your insurer requires.
