AI-first, agent-first DMARC software

DMARC software that does the work

Palisade is the easiest way for IT teams to reach DMARC enforcement, from one domain to thousands. Its AI agent investigates sending sources, configures SPF and DKIM, and moves domains toward p=reject, with DNS integrations that do the setup for you. Traditional DMARC workflows organize reports and leave each change to an operator.

The decision

Which one is right for you?

Pick Mailhardener if…

  • You prefer a more traditional Mailhardener workflow with people involved in each enforcement step.
  • Your buying criteria center on vendor-specific enterprise requirements.
  • Pick Mailhardener if you are a small EU-billed team that wants DMARC and SMTP TLS monitoring plus MTA-STS and BIMI hosting at a flat plan price, and you are comfortable making DNS policy changes yourself.
  • Pick Mailhardener if your MSP runs a large book of monitor-only domains and has the engineering hours to handle enforcement manually; its €1 per domain rate becomes the cheaper line item once the €149 base fee is spread over enough client domains.

Pick Palisade if…

  • You manage anywhere from one domain to thousands.
  • You want an AI agent to investigate issues, configure authentication, and move domains toward p=reject.
  • Teams already using Claude, OpenAI, or other AI tools can bring the same agent-led operating model to DMARC.

Monitoring and hosting, or executed enforcement

Mailhardener collects DMARC aggregate and SMTP TLS reports, monitors your DNS records, and hosts MTA-STS policies and BIMI assets. The workflow it describes is visibility-first: the platform surfaces what its monitoring finds, then your team interprets the reports and makes the SPF, DKIM and DMARC changes in DNS. Mailhardener does not advertise automated policy enforcement or automatic movement to p=reject (checked 2026-07-18).

Palisade runs that loop for you. An autonomous agent identifies legitimate senders from report data, configures SPF and DKIM for each source, and progressively tightens the DMARC policy until the domain reaches p=reject. The difference is where the work lands: with Mailhardener the analysis and every DNS edit stay with your engineers, while Palisade executes enforcement and leaves your team to review outcomes.

What Mailhardener meters (and what Palisade does not)

Mailhardener meters by domain count and data retention. Free covers one domain with one month of history, Standard caps at 10 domains and three months, Large at 100 domains and one year, and unlimited retention sits behind the quote-based Enterprise package. API access is included by default only on Large, Enterprise and MSP. The MSP package removes the domain caps but adds a €149 monthly base fee plus €1 per domain.

Palisade prices on domains alone: $9 per domain per month for domains 2 through 100, $7 from 100 to 1,000, and $5 beyond that, with annual billing taking $2 off every tier. There is no base fee, and every paid plan carries unlimited email volume and unlimited report retention. API access comes with every plan, including the free NFR domain for your own MSP, and the 15-day trial needs no card.

Where Mailhardener fits, and where MSPs outgrow it

Mailhardener serves EU-billed teams that want authentication monitoring with MTA-STS and BIMI hosting at a flat plan price. Its MSP package adds isolated customer environments, white-label reports and a CSV billing breakdown. That combination works for a provider whose clients mostly need visibility, where an engineer can review each tenant's reports and apply the DNS changes by hand.

The model strains as the client count grows. Every enforcement decision across every tenant remains a manual task. Mailhardener's pricing page lists 'PSA integrations' among its MSP package features, but it does not name ConnectWise, HaloPSA or Autotask anywhere on its public pages (checked 2026-07-18). The honest concession: an MSP managing a large book of monitor-only domains, with staff hours to spare for DNS work, will find Mailhardener's €1 per domain rate the cheaper line item.

Migration

Switching from Mailhardener takes three steps

1

Batch-import your domains

Bring your client domains into Palisade in bulk, or let your ConnectWise, HaloPSA, or Autotask integration sync them automatically.

2

Run both platforms in parallel

DMARC reporting supports multiple recipients, so Palisade and Mailhardener receive the same reports during the overlap window. Nothing breaks while you compare.

3

Cut DNS over on your schedule

Point records at Palisade's hosted infrastructure (100% DNS uptime guarantee), then retire the old setup when you're satisfied.

Questions

Palisade vs Mailhardener: FAQ

Palisade is AI-first and agent-first DMARC software. Its agent investigates sending sources, works through SPF and DKIM alignment, and moves domains toward p=reject while your team stays in control. When evaluating Mailhardener, compare that operating model with the workflow in its current product documentation and decide how much work you want your team to carry.

Choose Palisade if you want an AI agent to carry routine DMARC work through enforcement, whether you manage one domain or thousands. It is also a natural fit for teams already using Claude, OpenAI, or other AI tools to get operational work done.

Choose Mailhardener if its current integrations, procurement model, or operating workflow better match your requirements. A more operator-led platform can also fit a team that prefers to review reports and make each change itself.

Start with a small group of representative domains. Send aggregate reports to both platforms during the evaluation, verify every legitimate sending source, and compare the work required to reach a safe enforcement decision. Confirm current pricing, retention, integrations, and contract terms directly with both vendors before migrating the rest of your portfolio.

No responsible DMARC platform should promise the same enforcement timeline for every domain. Timing depends on the number of sending sources, access to DNS and third-party systems, and how quickly each legitimate stream can be aligned. Palisade's agent reduces routine investigation and configuration work while operators retain control over policy decisions.
