Lock down who gets in
Enforce MFA everywhere, set up conditional access policies, protect admin accounts with dedicated controls, block risky sign-in behaviour and remove stale or over-privileged accounts.
Microsoft 365 tenant hardening
Your Microsoft 365 is almost certainly wide open
Right now, the security controls inside your Microsoft 365 subscription are either switched off, set to their weakest defaults, or misconfigured. That’s not a guess — it’s what we find in almost every tenant we assess. Attackers know it too. We lock it down.
- We configure, tune and lock down the security you’re already paying for.
- Close the exact gaps attackers use to get in: weak logins, open email, unmanaged devices.
- Evidence pack for cyber insurance, Cyber Essentials and client due diligence.
- Every change documented so your team understands and owns it.
Why this matters
A single compromised Microsoft 365 account can give an attacker access to your email, your files, your contacts and your financial systems — in minutes. Most SME breaches don’t start with sophisticated hacking. They start with a stolen password, a phishing link, or a device that was never enrolled into management.
The tools to stop all three are already inside your Microsoft subscription. They’re just not switched on.
We go through your Microsoft 365 and lock every door
Our Microsoft security engineers audit your tenant, switch on the controls you’re paying for but not using, and close the gaps attackers walk through every day.
Harden your email
Configure anti-phishing, safe links, safe attachments and anti-spoofing policies in Exchange Online — so your email filtering actually catches the threats Microsoft misses by default.
Control every device
Enrol devices into Intune, enforce compliance baselines, turn on disk encryption, configure endpoint protection and make sure only trusted devices can access company data.
Stop data walking out
Lock down external sharing in SharePoint and OneDrive, apply sensitivity labels where they matter, enable audit logging and set retention policies so nothing leaves without a trace.
See threats as they happen
Turn on and tune Microsoft’s built-in threat detection — alerting on suspicious sign-ins, impossible travel, risky user behaviour and compromised account indicators.
Prove it to auditors
Configure the logging, retention and evidence that insurers, auditors and compliance frameworks like Cyber Essentials, ISO 27001, NIST CSF and HIPAA expect to see.
You’re already paying for the protection. You’re just not using it.
Your Microsoft licence already includes serious security tools — the higher the tier, the more you get. The problem is that most organisations use less than 20% of what they’re paying for. We switch on and configure what’s already there.
Stops the attacks that actually hit SMEs
Credential theft, phishing and unmanaged devices cause the vast majority of real-world SME breaches. Not sophisticated zero-days — basic gaps that hardening closes completely, using controls you already own.
Your insurer already expects it
MFA, email protection, endpoint management and audit logging are baseline requirements on cyber insurance applications. Without them, you’re paying more for cover, getting less of it, or being declined altogether.
No new products, no new cost
Every control we configure is already included in your Microsoft licence — whether that’s Business Premium, Business Premium with the Defender & Purview add-on, or E5. No new products, no new monthly costs. We just switch on and tune what’s already there.
Visibility you don’t have today
If someone compromised an admin account in your tenant right now, would you know? Audit logging, sign-in monitoring and admin activity tracking turn your environment from a black box into something you can see and respond to.
Shrinks your attack surface overnight
Legacy protocols disabled. External sharing restricted. Risky sign-ins blocked. Unmanaged devices locked out. Every door we close is one less way in — and most are wide open in a default tenant.
Evidence, not promises
Every policy and setting is documented in plain English. When your insurer, your auditor, or a client due-diligence questionnaire asks “what security controls do you have in place?” — you hand them the pack instead of scrambling.
Built around your tenant, not a generic checklist
Every engagement is led by senior Microsoft engineers who work in Entra, Intune, Defender and Purview every day — not a first-line team running through a checklist.
Audit & prioritise
We map your tenant — identities, devices, admin roles, sharing settings and licence allocation — then sequence the work around the controls that will reduce your risk fastest. You see exactly what’s exposed and what we’ll fix first.
Roll out safely
Changes land in monitor mode first, then a pilot group, then full enforcement — with a back-out plan at every stage. Your users shouldn’t notice the hardening happening around them.
Document & hand over
Every policy, setting and exception goes into a plain-English handover pack — plus a prioritised roadmap of what’s been hardened, what’s been deferred and what to tackle next. Your team, your auditor and your insurer can see exactly what changed and why.
Ongoing support
Microsoft changes constantly. We can continue to monitor your Secure Score, review new policies as they land, and adjust controls as your organisation grows — so the investment keeps paying off long after the initial engagement ends.
Go further where it makes sense
Microsoft’s native security covers a lot of ground, but some organisations need more. We recommend which extras are worth it based on what we find during discovery.
Advanced email security
API-based email security that sits alongside Exchange Online for advanced phishing, BEC and malware protection beyond what Microsoft’s built-in filters catch.
Domain authentication (DMARC)
SPF, DKIM and DMARC deployed and progressively enforced so attackers can’t send fake emails from your domain — with clear reporting on who’s trying.
DNS-layer web filtering
Blocks malicious domains, phishing sites and inappropriate content at the DNS layer — in the office, at home and on the move.
Managed identity threat detection
24/7 human-led investigation of suspicious sign-ins and session activity in Microsoft 365 and Entra ID, on top of Microsoft’s native controls.
Independent cloud backup
Independent backup of Exchange, SharePoint, OneDrive and Teams to tamper-proof cloud storage — recoverable even if the tenant is fully compromised.
