The problem

You are running a firm, not an IT shop.

Your team logs into Microsoft 365, Google Workspace, maybe AWS or Cloudflare. Each one is a door. When something looks wrong on one of those doors at eleven at night on a Sunday, nobody is watching.

We are.

Why now

Three things changed this year.

Regulators, insurers, and attackers all caught up with small business at the same time.

$0 /day
FTC Safeguards Rule, 2026
The FTC is fining firms your size
CPAs, tax preparers, mortgage brokers, financial advisors, insurance agencies, and auto dealerships are all covered. Most do not realize it. We monitor and document the access and authentication evidence the rule asks for.
0% of denied claims
Coalition 2024 cyber claims data
Your underwriter wants proof at renewal
Most denied cyber insurance claims involved organizations without documented MFA. We generate the monitoring evidence underwriters now ask for, automatically, in time for renewal.
0M records exposed
LexisNexis Legal & Professional, March 2026
SaaS auth is the new perimeter
Even the legal industry's largest research vendor was breached this year. We watch the auth layer your DocketWise, Clio, Lacerte, or QuickBooks Online login depends on, in real time.
What we watch

Four cloud doors. Specific incidents.

Not capability lists. The actual things that happen when something goes wrong.

Microsoft 365 LIVE
Compromised mailbox rules, sign-ins from new countries, mass file deletions in OneDrive, suspicious mail forwarding.
Google Workspace LIVE
Unusual admin activity, OAuth grants to unknown apps, Drive sharing anomalies, account takeover patterns.
AWS LIVE
Root account use, public S3 buckets, IAM privilege escalation, unusual API spikes from unknown regions.
Cloudflare LIVE
DNS record changes, WAF bypass patterns, exposed origin servers, certificate misissues.

Local roots, real accountability

Behind every alert is a founder you can call.

Cole Kingsley, founder of SentinelSMB

“The engines watch around the clock. When an alert needs a human, the reply comes from me — not a ticket queue.”

Cole Kingsley · Founder, SentinelSMB

SentinelSMB is built and run from Bismarck, North Dakota — every engine, every alert, every line of code, by one local founder. No tier-one queue. No off-shore support. No anonymous email-only relationship.

And because I built it myself, I can keep building. When your firm grows, when you adopt a new tool, when a regulator changes the rules — the platform grows with you. Tell me what you need to see in the dashboard. I am the person who can ship it.

  • North Dakota LLC, EIN on file
  • E&O insured to $2M aggregate
  • Founder-direct email response
  • Plain-English answers, no jargon
  • Built by one founder, every line

FAQ

Plain answers to fair questions.

If your IT provider is doing 24/7 cybersecurity monitoring across Microsoft 365, Google Workspace, AWS, and Cloudflare with documented response steps, you do not need us. If they are not, or if you are not sure, we layer in alongside them. We share alerts with your IT contact directly and we make their job easier, not harder.
Under ten minutes for a single integration. Microsoft 365 and Google Workspace are an OAuth approval. AWS is a CloudFormation template you paste a Role ARN from. Cloudflare is an API token. No agent on any computer. No appliance to ship.
We charge the card on file at the tier you picked. You can cancel anytime from inside the dashboard. There is no annual commitment.
Every alert includes guided response steps in plain English. The first three or four are usually things you can do yourself in a few minutes. If it is bigger than that, Pro tier includes consulting calls so a human walks you through it.
Not yet. Healthcare is on the roadmap, but it is walled off until our subprocessor BAA chain is fully executed. If you are a covered entity or business associate, please wait for that announcement before signing up.
