ShieldLine is a small cybersecurity practice in Chicago. We exist for one reason: small businesses run on their websites — bookings, payments, client data — and they are the ones hackers actually target. Big security firms don't serve them. We do.
ShieldLine is run by Mike (Chicago). You can call 773-573-4908 or email mike@shieldlinesecurity.com and talk to a human — not a ticket queue.
672 N Dearborn St, Chicago, IL 60654. Every email we send carries our physical address, as the law requires — because we have nothing to hide.
Breach checks use Have I Been Pwned (the industry standard), SSL grades use Qualys SSL Labs, and scanning uses the same public-data techniques security researchers use everywhere.
We only scan what you ask us to scan, or what is publicly visible — we never probe, exploit, or touch anything behind a login without written authorization.
Prices are published on this site. The free scan is free forever. Subscriptions are paid through Stripe and can be cancelled anytime — you keep access until the period ends.
If we reach out, it's one honest email with a working one-click unsubscribe. If you scan and do nothing, nothing happens — no follow-up spam.
We're a young company, not a Fortune 500 security giant. That's the point — you get the founder's attention, not a call-center script. Every claim we make on this site is verifiable: call us, email us, run a scan, read a report. If something's broken, tell us — we fix it fast and we'll tell you how we fixed it.
Run a free scan on your own website and read the report. No card, no call, no signup wall.
