The free tools.
Four real scanners, not a quiz that emails you a “risk score.” Point one at a domain you already understand and see whether we agree with you. No form, no login, no call. Email is optional and only if you want the full PDF.
These are the scanners we built for our own practice and left open to the public. They are the fastest way to judge whether we know what we are doing before you speak to anyone here.
Four scanners. Four honest grades.
Each one answers a question a client has actually asked us, in a form you can forward without editing. Run them on your own domain first, then on the prospect you have been circling for six months.
Argos LENS
FreeAn external cyber scorecard for any domain — exposed services and attack surface, email authentication, breach and dark-web credential exposure, and the specific findings that start a real conversation with an owner who thinks they are fine.
A grade in seconds · no account
Run Argos Lens →Argos DOPPLER
FreeWhether a domain can be spoofed, and by whom. SPF, DKIM and DMARC posture explained in language a business owner can act on, with a branded PDF you can hand to a client without rewriting it first.
A grade in seconds · no account
Run Argos Doppler →Argos SITE HEALTH
FreeA real crawl of the whole site — not one page — covering security headers and TLS, broken links, performance, accessibility and SEO hygiene. It takes about a minute, because it is actually visiting the pages.
About a minute · no account
Run Argos Site Health →Argos EXPOSURE
FreeWhether an email address or a whole domain appears in a known data breach — and whether a specific password has leaked, tested privately in your own browser so the password itself never leaves it.
A grade in seconds · no account
Run Argos Exposure →The gated “free assessment.”
You know the pattern. A landing page promises a free security assessment, collects your name, your work email, your phone number, your company size and your budget range, and then sends you a calendar link. The report arrives after the call, if at all. That is not a scan. It is a lead form wearing a lab coat.
- Hold your results hostage behind a “book a call to see your score.”
- Require a business email before a single check runs.
- Score every domain red so the follow-up call writes itself.
- Enroll you in a nurture sequence you did not ask for because you scanned a domain once.
- Meter the tool after you get used to it and call the meter a “free tier.”
- You enter a domain. The scan runs. The grade appears on your screen.
- If the domain is in decent shape, the grade says so. A scanner that never returns a good result is a sales tool, not a scanner.
- Email is asked for once, optionally, and only to deliver the full PDF report.
- You can run it on a competitor, on a prospect, or on us. We are not going to stop you.
The tactics we will not use are written down and published on the No-Tricks Pledge, so this paragraph is enforceable rather than decorative.
Do not read this section.
Go run one instead.
This is the only page on this website where the proof is not a number in a ledger — it is a link. Everything above can be tested by you, right now, in less time than it takes to finish this paragraph.
A suggestion. Run one against a domain you know intimately — your own, or a client you have managed for five years. You already know what the answer should be. If we tell you something you know to be wrong, you have learned everything you need to know about us for free, in under a minute, and you can close the tab.
That is the trade we are offering on this page. It is the same trade as the rest of the site: don’t trust us, check us.
On this page: nothing.
Every other product page on this site fills this slot with a structural claim — something a competitor cannot retrofit without rewriting their architecture. The free tools do not have one, so rather than manufacture something, here is the truth.
Plenty of vendors publish free scanners. Several of them are good. The checks we run — DNS and email authentication, header and TLS inspection, breach corpus lookups, crawl-based site auditing — are well understood techniques, and we did not invent any of them.
The only difference here is the gate, and a gate is a policy, not an architecture. Somebody else could adopt it tomorrow. We would consider that a good outcome.
We are telling you this on a marketing page because a company that will inflate a claim about a free tool will inflate a claim about a platform you are betting your practice on.
Passwords never leave your browser. Exposure checks a password using a partial-hash lookup, so the password itself is never transmitted to us or to anyone else. That is the correct way to build it rather than a clever one — we mention it only so you know we did not take the shortcut.
Site Health actually crawls. Most “website audits” grade one page and extrapolate. Ours visits the site, which is why it takes about a minute instead of returning a number immediately.
Neither is a moat. Both are the reason the grades are worth reading.
A grade, the findings behind it,
and no one calling you.
These tools are open to anyone, including people who will never buy anything from us. That is deliberate. They also happen to be the front door to the platform, so here is exactly what happens on the other side of one.
- A letter grade, and the specific findings that produced it — not a score with no arithmetic behind it.
- Severity, plain-English explanation, and what to do about it, in the order that matters.
- A shareable result you can put in front of a client or a prospect without a slide deck around it.
- An optional full PDF report, branded, delivered to an email address only if you choose to give one.
The same checks run continuously inside the platform. Lens and Doppler findings become monitored posture in Argos Red, exposure findings become identity work in Argos Identity, and all of it becomes live evidence in Argos GRC against the frameworks your clients are audited on.
One scan is a snapshot. The platform is the same question asked every day, against the same client object, with the answer landing in a service desk that can act on it.
And if you never take that step, the scanners stay free and unmetered anyway. Zero• Argos OS customers today — we are not counting on you being the exception.
