SkyQon vs Red Sift, compared honestly

Looking for a Red Sift alternative? Here's the honest comparison.

Q: Is SkyQon a good alternative to Red Sift?

Yes, if what you need is the whole external trust surface — email authentication, DNS security, TLS and certificates, subdomains, registrar and brand monitoring — in one self-serve product with signed, auditor-verifiable evidence and EU data residency. If you specifically need a managed enterprise DMARC rollout or end-to-end BIMI with VMC provisioning, Red Sift OnDMARC is a strong product for that job.

Q: Can I try SkyQon before leaving Red Sift?

Yes, and you should: SkyQon's free tier monitors up to 5 domains continuously with no card and no agent, so you can run both side by side and compare findings on your own estate before deciding anything.

Red Sift is a strong UK-based email-security platform. If you need a managed enterprise DMARC rollout across a complex email estate, or end-to-end BIMI with VMC provisioning, it is a fine choice. SkyQon is the EU alternative for when the question is bigger than email: the whole external trust surface (email authentication, DNS security, TLS and certificates, subdomains, registrar and brand) in one self-serve product, with evidence an auditor can verify. Every SkyQon report is PAdES-signed with a public verifier, and customer data stays in the EU: two lines a NIS2 or DORA buyer can put straight into a supplier register.

Who should pick which?

A comparison you can trust has to name the cases where the other product wins. Here they are.

Pick Red Sift if…

You are running a managed DMARC enforcement programme across a large, complex email estate and want a specialist to guide it (OnDMARC is very good at exactly that), or you need end-to-end BIMI with VMC provisioning. If OnDMARC already works for you and email is your whole problem, switching buys you little.

Pick SkyQon if…

EU data residency is a requirement, an auditor, insurer or enterprise customer is asking for evidence rather than screenshots, or you want email, DNS, certificates, subdomains, registrar and brand covered by one subscription instead of assembling modular products. SkyQon is self-serve from €0: no sales call to find out the price.

Coming from Hardenize?

Red Sift acquired Hardenize in October 2022. Hardenize still runs, but its Business and Enterprise plans are sold through a demo request, with no price on the page. Red Sift's free option today is Certificates Lite: up to 250 certificates, scanned daily on port 443, with an alert 7 days before expiry. If you used Hardenize to watch the whole posture of a handful of domains, beyond certificate expiry, SkyQon's free tier (5 domains, the whole surface, continuous, no card) is the closest thing to getting that back.

What does Red Sift say about itself?

Fairness check: Red Sift describes its mission as "Creating a Fundamentally Safer Internet with Proactive Security" (redsift.com), and OnDMARC as guided, tiered email protection from SMB to enterprise. Those descriptions are accurate: it is a capable platform with a long DMARC track record. The difference is not quality; it is scope, jurisdiction and what you can hand to an auditor afterwards.

How hard is it to switch?

Your records are yours

SPF, DKIM and DMARC live in your DNS, not in any vendor. Adding your domains to SkyQon changes nothing about your email flow. It reads what is already public and scores it. There is no lock-in on either side for the core records.

One thing to check first

If you use Red Sift's hosted records (hosted MTA-STS or BIMI, for example), those live on their infrastructure. Repoint or replace them before you cancel, not after, so nothing breaks in between.

Run both, then decide

SkyQon's free tier means the migration can start as a comparison: monitor the same domains in both tools for a month, compare findings and alerts on your real estate, and let the results make the decision.

SkyQon vs Red Sift: frequently asked questions

Is SkyQon a good alternative to Red Sift?

Yes, if what you need is the whole external trust surface (email authentication, DNS security, TLS and certificates, subdomains, registrar and brand monitoring) in one self-serve product with signed, auditor-verifiable evidence and EU data residency. If you specifically need a managed enterprise DMARC rollout or end-to-end BIMI with VMC provisioning, Red Sift OnDMARC is a strong product for that job.

Is Red Sift better than SkyQon for DMARC?

For a large, complex email estate where you want a managed, guided DMARC enforcement programme, OnDMARC is excellent and may be the better pick. SkyQon covers SPF, DKIM, DMARC, MTA-STS and BIMI fully (including enforcement depth and exact copy-paste records) as one part of a broader domain trust platform rather than as a standalone specialist tool.

What happened to Hardenize?

Red Sift acquired Hardenize in October 2022. Hardenize still runs and its public report still works on a single domain, but its Business and Enterprise plans are sold through a demo request, with no plan price shown. Red Sift's free option today is Certificates Lite: up to 250 certificates, scanned daily on port 443, with an alert 7 days before expiry. SkyQon's free tier, continuous monitoring of up to 5 domains covering email authentication, DNS security and certificates together, is the closest direct replacement for how most people used Hardenize.

Does Red Sift store data in the EU?

Red Sift's privacy policy names Redsift Limited, with a London address, as the company handling your data under UK GDPR, and allows transfers outside the UK and EEA, including to the United States. For customer data, it refers to a separate data processing addendum. The UK is a third country under EU law, currently covered by an adequacy decision. SkyQon is EU-based and stores customer data in the EU, a line you can put directly into a NIS2 or DORA supplier register.

Can I try SkyQon before leaving Red Sift?

Yes, and you should: the free tier monitors up to 5 domains continuously with no card and no agent, so you can run both side by side and compare findings on your own estate before deciding anything.

How much does SkyQon cost compared to Red Sift?

SkyQon publishes every price: Free at €0 for up to 5 domains, Starter at €39/mo, Pro at €149/mo, Growth at €599/mo, with annual discounts, for the whole trust surface in one product. Red Sift publishes one self-serve price, OnDMARC Express from $9/month billed annually for up to 4 domains, and offers Certificates Lite free. Its other plans and products go through sales; check their pricing pages for current figures.

Can an auditor verify SkyQon reports without an account?

Yes. Every SkyQon compliance report is PAdES-signed and carries a SHA-256 content hash; anyone can validate a report at our public verifier, with no account. Lifecycle actions are recorded in a hash-chained ledger, so the whole sequence (detect, replace, revoke) can be verified, along with the end state.
