AOITSec Email Security

One DNS Record. Fully Managed, Forever.

Email authentication normally means editing raw DNS records yourself, and getting it wrong is easy: miss the SPF lookup limit, misconfigure a DMARC policy, or let a signing key go stale, and your email starts landing in spam or gets spoofed entirely. AOITSec flips that. You add one DNS record, once, and our team manages everything behind it from then on, policy changes, key rotation, SPF flattening, report handling, all of it, with no further DNS work on your side.

The DNS Problem Nobody Has Time For

Modern businesses send email through more services than they realise: Google Workspace or Microsoft 365, plus Salesforce, Mailchimp, HubSpot, a helpdesk tool, a billing system. Each one needs to be authorised to send as your domain, and SPF allows only 10 DNS lookups before it fails outright. Businesses using several tools routinely find themselves over that limit without knowing it, silently breaking their own email authentication.

DMARC, MTA-STS, TLS-RPT and BIMI each add their own configuration, their own DNS records, and their own ongoing maintenance, and DKIM signing keys need checking and rotating on top of that. Sending IPs change as providers update their infrastructure. Reports need to be collected and read. None of this is a one-off job, it is an ongoing responsibility that most businesses do not have the time or expertise to keep on top of.

AOITSec removes that burden entirely. You add a small set of DNS records once, and our platform and team take full ownership of keeping your email authentication correct, secure and up to date, permanently.

Every Layer of Email Authentication, Fully Managed

Five protocols hosted and managed end to end, with DKIM verification included as part of your ongoing monitoring. You add one DNS record per service, once, and we handle everything else.

Hosted DMARC

We set your DMARC policy, monitor who is sending as your domain, and manage every subsequent policy change ourselves. Aggregate and forensic reports are collected and reviewed on your behalf, so you never have to read raw report data yourself.

Hosted SPF, Flattened

We resolve every sending source you use down to a single, permanently compliant SPF record, regardless of how many tools you rely on. As those services change their sending infrastructure, we re-flatten your record automatically, so it never breaks.

Find out more

Hosted MTA-STS

We manage the policy, hosting and certificate work MTA-STS requires to enforce encrypted delivery to your mail servers, infrastructure most businesses would otherwise need to build and maintain themselves.

Find out more

Hosted TLS-RPT

We collect and interpret the reports that show when encrypted delivery to your domain has failed, so you know about delivery problems before they become a pattern.

Find out more

Hosted BIMI

Once your DMARC policy is strong enough to qualify, we manage your verified brand logo so it appears alongside your authenticated emails in supporting inboxes, a visible sign to your customers that a message is genuinely from you.

One Score for Your Whole Domain

Every domain gets a single, plain-English health grade covering DMARC, SPF, DKIM, MTA-STS, TLS-RPT and BIMI together, with a prioritised list of anything that needs attention, not just a wall of technical data.

Reliability and Automation Built In

Every managed record is re-checked against live DNS every few hours, and your SPF record is automatically re-flattened as the services you use change their sending infrastructure, so your configuration never quietly drifts out of date.

Non-Destructive by Design

Before we change anything, we take a full snapshot of your original DNS configuration. If you ever want to step back, a full revert is always available, so managing this with us is never a one-way door.

Managed End to End, With Access If You Want It

AOITSec is our own platform, built because we were tired of paying for overpriced tools that did what we knew we could build better ourselves. By default, we manage the whole thing for you, configuration, changes, monitoring and reporting, so email authentication is simply never something you have to think about.

If you would rather make quick changes yourself from time to time, we can give you access to the dashboard directly, but nothing about the service depends on you using it. The same platform lets our team manage many client domains from a single place, so however many domains your business has, they are handled with the same level of oversight.

The platform runs on enterprise-grade infrastructure, with every credential encrypted at rest, so the foundation underneath your email authentication is as carefully managed as the configuration itself.

There to help even if you're not sure what to do!

AOIT are always there to help, even when I wasn't sure what the solution is! A few weeks ago, I tried to call a contact. The outbound call didn't work, so I dropped them a text, and they were unable to reach me either. Having worked with Andrew a few times previously, I decided to get in touch with him, even though it was none of his equipment causing issues.

Frequently Asked Questions

AOITSec is a platform built and operated by AOIT Networks that manages email authentication for your business, hosting and managing DMARC, SPF, MTA-STS, TLS-RPT and BIMI, and verifying your DKIM configuration, all from one place.

Only once. You add a small set of DNS records pointing at our platform, and every configuration change after that, policy updates, key rotation, SPF changes, is handled by us without any further DNS work on your side.

SPF only allows 10 DNS lookups before it fails outright. Flattening resolves every service you use down to raw IP addresses and rebuilds your SPF record as a single lookup, so adding more email tools never risks breaking your authentication.

It is exactly the problem AOITSec is built to solve. Businesses using several sending services often exceed SPF's lookup limit without realising it. We flatten your SPF record so it stays valid regardless of how many services you rely on.

Yes, if you want to make quick changes yourself, we can give you access. Most of our clients are happy to leave it entirely to us, but the option is there.

We take a full snapshot of your original DNS configuration before we change anything. A complete revert is always available, so nothing we do is irreversible.

It is a single, plain-English grade covering DMARC, SPF, DKIM, MTA-STS, TLS-RPT and BIMI, together with a prioritised list of anything that still needs attention.

Yes. Subdomains are covered automatically, and where mail is seen coming from a subdomain you never explicitly registered, it gets picked up and brought under management rather than left unprotected.

Yes. The platform runs on enterprise-grade infrastructure, and all credentials and access keys are encrypted at rest.

Yes. The platform is built to manage many domains from a single place, with the same level of monitoring and control whether you have one domain or dozens.
