A & G service

Email Security

Stop phishing and spam before they reach the inbox — filtering, authentication, and staff training.

How A & G works

Discover / Assess / Improve
  • Understand what the business needs from technology
  • Design and deploy the right improvements
  • Manage, document, and improve the environment over time

Most breaches we are called to clean up started in an inbox — a phished credential, a forwarding rule you did not set, an invoice that was not. Spam filters catch volume; they do not fix a domain that can be spoofed, a mailbox an attacker already controls, or the one message that only needs a single click. We lock down the email layer properly: authentication, accounts, and the rules hiding inside mailboxes.

The goal is email your staff can trust without thinking about it: spoofed senders stopped at the door, compromised accounts caught and cleaned up, and phishing risk reduced while email stays easy to use.

What this service includes

  • SPF, DKIM, and DMARC review and correction — so your domain is hard to spoof
  • Mailbox rule audit — hunting the suspicious forwarding rules attackers leave behind
  • MFA enforcement and account recovery hardening
  • Compromised mailbox cleanup — containing it, recovering it, and closing the hole
  • Phishing-risk reduction that keeps email usable for staff

Problems we fix

  • Phishing emails that sail straight through to inboxes
  • A domain with no SPF, DKIM, or DMARC — or records set up wrong
  • Suspicious forwarding rules hiding in mailboxes
  • Compromised accounts with weak recovery settings
  • Staff who cannot tell a real invoice email from a fake one

Platforms and environments

Microsoft 365 and Google Workspace mail, plus the DNS records (SPF, DKIM, DMARC) that protect your domain — and the vendors, phones, cameras, and conference tools around them when an incident touches more than email.

Frequently asked questions

We already have spam filtering — isn’t that enough?

Filtering catches volume. It does not fix a spoofable domain, a compromised account, or the forwarding rule an attacker added to a mailbox. We cover the rest.

Will this make email harder to use?

No. The goal is fewer dangerous messages and clearer signals — not more hoops for your staff.

Can you tell if we have already been compromised?

Usually, yes. We review mailbox rules, forwarding, login activity, and authentication records for the signs, then contain and clean up what we find.

The experience behind it

We have cleaned up compromised mailboxes and traced spoofed senders for businesses that thought their email was fine — until it was not. You work directly with a 25-year specialist — the person who audits your mail is the person you talk to.

Your inbox is the front door. Book online for an email security review — or call and tell us what landed in your inbox this week.
