Prefer to buy through Microsoft?
Tenant Strike is listed on the Microsoft commercial marketplace, so you can subscribe on your existing Microsoft billing account — same plans, same prices — and draw down Azure committed spend if you have it. Cancel from the Azure portal any time. View our Microsoft listing →
Quarterly Security Review
Pay for Pro yearly and we sit down with you up to four times a year — 45 minutes, scheduled when it suits you — and go through what changed, what it means, and the two or three things actually worth doing next quarter. You get the judgment part of a security firm without the retainer.
- What changed since last quarter, and whether it mattered
- A short, prioritized plan you can hand to whoever does the work
- Straight answers on findings you've accepted or deferred
- Written follow-up you can forward to your board or insurer
Monthly Pro and Basic don’t include reviews — but you can still email us any time, and we answer. If your Microsoft tenants are managed by an IT provider, your reviews come from them rather than us — that’s what they’re there for.
