Looking for a Red Sift alternative? Here's the honest comparison.
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.
- Signed, auditor-verifiable reports — not just dashboards
- EU company, EU data residency, mapped to NIS2, DORA and eIDAS
- One product and one price for the whole domain estate, from €0

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 and folded it into its enterprise products; in summer 2026 self-serve returned for certificates only (Certificates Lite free, Certificates Essentials from $99/mo). If you used Hardenize to watch the whole posture of a handful of domains — not just certificate expiry — SkyQon's free tier — 5 domains, full surface, continuous, no card — is the closest thing to getting that back.
SkyQon vs Red Sift, criterion by criterion
Facts below come from each company's own public pages, checked on the date above. For anything sales-led, we link rather than guess.
| Criterion | SkyQon | Red Sift |
|---|---|---|
| Evidence an auditor can verify | PAdES-signed reports with SHA-256 content hash, public verifier (no account needed), hash-chained lifecycle ledger | Dashboards and exports; no signed-report verifier advertised on its public pages |
| Jurisdiction & data residency | EU company; customer data stored in the EU | Redsift Limited, registered in London — a UK data controller (per its privacy policy) |
| Coverage in one product | Email auth, DNS/DNSSEC/CAA, TLS & certificates, CT log monitoring, subdomains, registrar, brand & look-alikes, post-quantum readiness, eIDAS checks — one subscription | Modular products licensed separately: OnDMARC, Certificates, ASM, Brand Trust, Radar |
| Remediation depth | Exact copy-paste DNS records and guided fixes; every finding visible even on Free | Strong guided DMARC remediation — a genuine strength of OnDMARC |
| Compliance evidence (NIS2 / DORA) | Signed NIS2/DORA technical-evidence reports and DORA supplier trust pages, built in | Not the product's focus; positioned as email security and brand protection |
| Price floor & buying model | All prices published: Free €0 (5 domains) · Starter €39/mo · Pro €149/mo — self-serve, no card to start | Certificates Lite free and Certificates Essentials from $99/mo (certificates only) are self-serve; OnDMARC Express from $9/mo billed annually; every other tier and product is sales-led — see their pricing pages |

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.
