How SkyQon compares
Every tool on this page does something well. We say what, and where SkyQon is different, so you can choose with your eyes open. The facts are dated, and we name the cases where the other tool is the better pick.
Facts checked against each company’s own public pages on 10 November 2026. Spotted an error? Tell us and we will correct it.
By kind of tool
Six kinds of tool overlap with SkyQon. For each one: what they do well, what SkyQon does instead, and when you should pick them.
DMARC-only tools
They do well: managed DMARC enforcement across large, messy email estates, with report analytics and hosted records.
SkyQon: SPF, DKIM, DMARC, MTA-STS, TLS-RPT and BIMI with the exact record to publish, in the same subscription as DNS, certificates, exposure and signed evidence.
Pick them if: email is your whole problem and you want a specialist to run the programme for you.
Certificate-expiry monitors
They do well: cheap expiry alerts on a list of hosts, from a few euros a month.
SkyQon: expiry plus issuer changes, Certificate Transparency alerts, chain and handshake detail, renewal on your own server, and a signed record of each fix.
Pick them if: all you need is a ping before a certificate expires.
One-shot free scanners
They do well: a deep, free, one-time grade of a single host.
SkyQon: the same view every day on all your domains, an alert when something changes, and the fix. Free for five domains, no account for the first check.
Pick them if: you want one thorough look at one host, today, and nothing after.
Attack-surface scanners
They do well: internet-wide discovery and very deep asset inventories, at enterprise prices.
SkyQon: exposure under domains you have proved and address ranges you consented to: open ports, devices that should not face the internet, old web software and the few known-exploited flaws we track. From Pro.
Pick them if: you need to discover assets you do not yet know you own.
GRC and compliance platforms
They do well: policies, controls, questionnaires and the audit workflow itself.
SkyQon: the technical evidence those controls point at, signed and verifiable by anyone. They are a complement, not a competitor; our reports can feed them.
Pick them if: you need the whole audit programme managed. Then hand them our evidence.
Certificate lifecycle (CLM) platforms
They do well: issuing and provisioning certificates to whole fleets from the certificate authorities they run or integrate.
SkyQon: watches from outside what they issued, flags every certificate where the records disagree, and manages your private CA at a smaller scale. We co-exist with them.
Pick them if: you issue thousands of certificates a day and already have the PKI team to run it.
Named comparisons
Three pages that name a product, criterion by criterion, with the cases where the other side wins and notes on switching.
SkyQon vs Red Sift
The one product with a real overlap: OnDMARC, Certificates, ASM and Brand Trust against one subscription. Evidence, jurisdiction, coverage, price floor, and where OnDMARC is the better pick.

SkyQon as a Hardenize alternative
Hardenize did not shut down, but whole-posture monitoring moved to quote-based tiers. What changed, what you can get back for free, and what to check before you move.

NCSC Mail Check and Web Check
The UK government service retired on 31 March 2026. The same checks, continuous, free for five domains, with the fix next to each finding.

Each named page carries the date its facts were last checked. A page older than 100 days cannot even be published: our build refuses it.
What only SkyQon does today
Six things we have not found together anywhere else. Each one is live in the product, not on a roadmap.
Evidence anyone can verify
NIS2 and DORA reports are signed and hashed. A public verifier checks them without an account. Your auditor does not have to trust us, or you.
Fixes confirmed by a later scan
A finding is marked fixed only when we see it gone. Each one becomes a signed record, so the fix is evidence too, not a note in a ticket.
eIDAS qualified certificates checked for real
QWAC and QSealC certificates are validated against the EU trusted lists of all 32 territories, refreshed daily. Not a badge, a check.
EU company, public prices, self-serve to Enterprise
Data stays in the EU. Every price is on the pricing page, and you can go from a free check to the top plan without a sales call. Talk to us if you want to; you do not have to.
Outside-in monitoring that also manages the certificates behind it
The same product that watches your public certificates renews them on your server, issues and revokes on your private CA, and reconciles what the CA issued against what is live.
A scanner you can look up and opt out of
Every probe leaves from one named server with its own page, its own reverse DNS and an abuse address, and any owner can opt a domain out. We scan the way we would want to be scanned.
How we keep this fair
- Every fact about another product comes from that company’s own public pages, and the page says on which date we read them.
- Where they publish nothing, we say “not published” instead of guessing.
- Every comparison names the cases where the other product is the better choice.
- A page whose facts are older than 100 days fails our build and cannot be published until someone re-checks it.
- If you work at one of these companies and something is wrong, write to us and we will correct it and say so.
