M365 & AD Hardening
Structured hardening of Microsoft 365 and Active Directory that closes common attack paths, protects identities, and raises your security baseline across cloud and on-prem.
Three defined packages. Staged rollout. Measurable results.
Most Microsoft environments run close to their default configuration, and attackers know it. Weak passwords, legacy protocols, and unprotected identities are still behind the majority of breaches we see. We harden your Microsoft 365 and Active Directory environment against exactly these attack paths, in close cooperation with your technical team and without disrupting daily operations. The result is documented, measurable, and yours to maintain.
Coverage
MFA enforced for every user and admin, phishing-resistant authentication, and legacy sign-in methods shut down for good.
Protection against phishing and malware across Exchange, Teams, SharePoint, and OneDrive, with external sharing under control.
Defender baselines, encryption, credential-theft protection, and legacy protocols removed from your internal network.
Audit policies and logging configured so that if something does happen, your team and ours can see it.
From current state to a measurably stronger baseline
We map your current configuration against the controls in your chosen package and confirm the scope.
Changes are prioritised and scheduled with your technical team so nothing surprises the business.
Controls are rolled out in stages, validated as we go, so daily operations keep running.
We measure the improvement, document every change, and walk your team through the new controls so the higher security level lasts.
Choose your level
M365 Starter + AD Essentials
The fast, safe first step, with minimal impact on everyday users. Best for smaller environments or a first structured move on security.
M365 Essentials + AD Full L1 Baseline
Broader protection for daily operations. Best for mid-sized organisations that want a standard, trusted baseline.
Full Syndis M365 baseline + AD Full L1 and L2
The highest security level we offer, built on Zero Trust principles. Best for organisations under regulatory oversight or certification requirements.
Data classification and data loss prevention for organisations handling sensitive information, including automated classification of Icelandic personal data.
Your daily operations live in the cloud. Make sure the doors are locked.
Cloud and on-prem AD side by side create attack paths most teams never see.
Demonstrate a documented, measurable security baseline to auditors and regulators.
Why Syndis
No. Changes are rolled out in stages and validated with your technical team before they reach the wider organisation. Most controls in the Starter package are invisible to everyday users.
No. Each package is a complete, coherent level of protection, and the higher packages include everything below them. We help you choose based on your environment, risk profile, and any regulatory requirements.
We measure your environment before and after the work using Microsoft's own security scoring, and deliver documentation of every change. The improvement is quantified, not claimed.
Yes. The packages are structured so the cloud and on-prem components can be scoped to your environment. Cloud-only organisations get the full M365 hardening without the AD components.
An assessment tells you what is wrong. Hardening fixes it. We do both: map the current state, implement the controls, and verify the result.
Tell us about your environment. We come back with scope and the package that fits.
