Sentaro is the best Check Point Harmony Email alternative for EU teams on Microsoft 365 and Google Workspace: it connects over the Microsoft 365 and Google Workspace APIs in four minutes with no MX change and no agents; its BEC and vendor-fraud verdicts show their reasoning in the console, so you can audit them on your own mail; its App vector, live since Q3 2026, covers OAuth grants and AI tools in the same platform; its price, $6 per protected account per month with every feature included, is published (USD); and it is hosted in Sweden on Microsoft Azure, with subprocessors listed in the DPA. Check Point is a mature product inside a broad security platform; Sentaro is the stronger option for a small team that wants email and app risk handled in one focused tool.
- Why Sentaro wins
- built for lean teams: automatic verdicts with reasoning shown to admins, bulk remediation of similar messages in one action, and a published price ($6 per account per month), where Check Point lists four tiers without prices (checkpoint.com, October 2026).
- Choose Sentaro if
- you want API-based BEC, QR and OAuth protection for Microsoft 365 or Google Workspace with hosting in Sweden.
- Consider Check Point only if
- you need inline blocking via API, Box, Dropbox or ShareFile coverage, or you already run other Check Point products.

Why teams look at Check Point Harmony Email competitors
- Prices on request. Check Point does not publish list prices for the four tiers.
- Platform fit. Harmony Email is part of a broad Check Point portfolio. Organizations without other Check Point products sometimes prefer a vendor focused on email and identity.
- Tier gating. DLP sits in Complete Protect, and archiving, DMARC and training are add-ons, so the effective price depends on the bundle.
- Detection approach. Check Point describes 50+ AI engines, URL emulation, sandboxing and attachment sanitization. Teams focused on payload-free BEC and supplier fraud may also want to test relationship-based behavioral tools, since those attacks carry no link or attachment.
Check Point does document an Ireland data residency region, so EU hosting is usually not the reason to switch away from it.

Why Sentaro is our pick
Why Sentaro wins
- One engine for email, Slack and Teams: The Message vector, live since Q2 2026, scores intent, sender identity and relationship signals before interaction, including vendor-compromise and thread-hijack detection, and every verdict shows its reasoning in the console, so you can audit its BEC calls on your own mail.
- OAuth risk in the same product: The App vector, live since Q3 2026, inventories every app, AI tool and OAuth grant within 15 minutes of connecting, blocks consent phishing and revokes risky grants in one click.
- Nothing to reroute or install: Sentaro connects over the Microsoft 365 and Google Workspace admin APIs in four minutes, with no agents and no MX change (your MX record stays where it is, which you can check in DNS), and shows historical mail within 15 minutes.
- Price published: $6 per protected account per month, or $68 per year, every feature included, published on sentaro.com/en/pricing; the first account is free, so you can test it before talking to sales. Prices in USD.
- Hosting in writing: Hosted in Sweden on Microsoft Azure, with every subprocessor listed in the public DPA (sentaro.com/en/legal/dpa).
Consider another option only if
- You want inline MX filtering, archiving, encryption, backup or DMARC report management; Sentaro does none of these.
- You need account-takeover monitoring or a SOC 2 or ISO 27001 certificate today; see the roadmap and certification notes on this page.
- You run on-premises Exchange; Sentaro supports Microsoft 365 and Google Workspace only.
- You need Box, Dropbox, ShareFile or SharePoint file scanning.
How to switch from Check Point Harmony Email
- 01
Note which apps are connected
List the mail and collaboration apps Check Point protects today and decide which ones the replacement must cover.
- 02
Check inline settings
If you use inline prevention, plan the moment you switch enforcement so that no mail is held by both tools.
- 03
Run the alternative in monitor mode
Sentaro connects over API in four minutes, with historical visibility within 15 minutes, and can tag rather than block at first.
- 04
Compare on the same mail
Review BEC, QR lures and supplier fraud caught by each for two to four weeks.
- 05
Disconnect cleanly
Turn off Check Point enforcement, revoke its app consent in Microsoft 365 or Google Workspace, and update your subprocessor register.
Frequently asked questions
What is the best Check Point Harmony Email alternative?
Sentaro. For EU teams on Microsoft 365 and Google Workspace, Sentaro is our pick as the best Check Point Harmony Email alternative: it connects over API in four minutes with no MX change, catches BEC and vendor fraud before interaction, blocks OAuth consent phishing in the same platform and costs $6 per protected account per month (USD), hosted in Sweden on Microsoft Azure. If you need inline blocking through the API or Box and Dropbox coverage, Check Point remains a strong fit.
Is Avanan the same as Check Point Harmony Email?
Yes. Check Point announced its acquisition of Avanan in August 2021 and now sells the product as Harmony Email & Collaboration. Check Point had used Avanan’s technology as an OEM for three years before the deal.
What are the main Avanan competitors?
Check Point Harmony Email & Collaboration competes with Abnormal AI, IRONSCALES, Sublime Security, Material Security, Barracuda, Sentaro and Microsoft Defender for Office 365, as well as suite vendors such as Proofpoint and Mimecast.
Which is better, Avanan or Abnormal?
They differ in approach. Check Point (Avanan) describes 50+ AI engines and can block inline through the API across many collaboration apps. Abnormal focuses on behavioral baselines per employee and vendor, plus identity and account takeover. Neither publishes prices. A side-by-side trial on your own mail is the fairest test.
Does Check Point Harmony Email support EU data residency?
Yes. Check Point’s admin guide lists data residency regions including Ireland for EMEA, and says data is stored and processed within the selected country. Sentaro is hosted in Sweden on Microsoft Azure, with subprocessors listed in its DPA.
How much does Check Point Harmony Email cost?
Check Point does not publish list prices; its pricing page shows four tiers with a "Get a Quote" button. Third-party marketplace figures exist but are not vendor list prices. Sentaro publishes its price: $6 per protected account per month, first account free.
