Tuck Sentinel
// Tuck Sentinel QuickCheck

Read-only audits. Written fixes. No calls.

I review one Linux host or one email domain, then hand you a prioritized report you can act on. No agents installed. No credentials stored. Most tiers turn around in about 24 hours after intake.

How it works

Designed around redacted evidence — not account takeover.

01 · Pay

Checkout on Stripe for a fixed scope. You get intake instructions by email.

02 · Send evidence

Screenshots, configs, headers, or safe outputs — not passwords or live keys. See authorization + sample.

03 · Get the report

Written findings, why they matter, and what to do next. Most standard tiers target ~24h after complete intake.

FAQ

Is this a pentest or compliance cert?

No. QuickCheck is a fixed-scope, read-only posture review and written advisory. It is not a penetration test, SOC 2, or a guarantee you are “unhackable.”

Do you need my passwords or SSH keys?

No. Prefer redacted evidence. If a review cannot complete without live access, we stop and redefine scope — we do not quietly expand into admin work.

What is the default recommendation?

Server Hardening Standard at $99 (launch price vs $149) for one Linux host. Choose Pilot ($49) for a lighter first pass, or Inbox/DNS ($99) when mail deliverability is the pain.

Turnaround?

Most single-host and single-domain tiers target about 24 hours after a complete intake package. Deep AI Cost Rescue can take longer; intake email will say.

Refunds?

See the refunds page. Standard policy includes a 14-day window on paid QuickChecks as stated in legal pages — read the linked terms before purchase.

All tiers are fixed-scope and async. No Zoom sales calls. After payment, follow the intake email. For authorization boundaries see the authorization page. *Refund details are governed by the refunds/terms pages, not this summary.
