Cybersecurity
Email remains the most common entry point for attacks. Mayer Networks layers filtering, domain authentication, identity protection, encryption and user training to reduce phishing and business email compromise.
Security lifecycle
Email security is a Protect control with a Detect component. It works on the delivery method most attacks against staff still use. See the full Mayer Networks cybersecurity approach.
What it is
Attackers do not need to defeat the firewall if they can send a convincing message to somebody who works there. Phishing, malicious links, malicious attachments, impersonation of executives and vendors, business email compromise, fraudulent payment requests and credential harvesting all arrive the same way.
Email security analyses messages for those characteristics: reputation, link destinations, attachment behaviour, sender authentication and impersonation patterns. Cloud email security inspects mail inside the Microsoft 365 environment rather than only at the gateway, which also means internal and already-delivered messages can be examined.
Default filtering stops bulk malicious mail. The targeted remainder is what this layer exists for.
The problem it solves
The messages that cause real loss usually look entirely reasonable.
How Mayer Networks uses it
Filtering is configured against real mail flow, and it is paired with the tenant configuration that decides how much damage a successful message can do.
Current filtering, authentication records, mailbox rules and identity protections are reviewed before anything is changed.
SPF, DKIM and DMARC are configured so spoofed mail claiming to be your organization is rejected rather than delivered.
Anti-phishing, malware detection, link inspection, attachment analysis and impersonation protection are deployed and tuned against the organization's actual mail, including legitimate senders that look unusual.
Forwarding rules, unusual sending behaviour and suspicious sign-ins are alerted on, because a compromised mailbox is often quieter than the phishing that created it.
A compromised account gets credential reset, session revocation, rule cleanup and a review of what was sent from it, coordinated with the wider incident process.
Ongoing awareness training and phishing simulation, because the targeted remainder is aimed at people rather than at filters.
Platform
Mayer Networks uses cloud email security to analyse messages in the Microsoft 365 environment, alongside the built-in Microsoft protections the tenant already licenses.
Cloud email security
Anti-phishing, malware and link analysis, attachment inspection, impersonation protection, policy control and alerting applied to mail inside the Microsoft 365 environment.
Configuration, not a product
External sender marking, legacy protocol restriction, forwarding controls and audit logging. Capability depends on the licensing the organization holds.
Check Point and Avanan are trademarks of Check Point Software Technologies Ltd. Capabilities depend on the licensed product tier and the tenant configuration.
Layered defence
Some messages will always reach people. The layers behind email are what decide the outcome when one does.
The payment-verification process is a business procedure rather than a product, and it prevents more loss than any single tool in this category.
Lifecycle stage: Protect and Detect
The layers most closely connected to this one. Each covers a front this control does not.
We can review filtering, domain authentication and mailbox settings, and show where a convincing message would still succeed today.
Review Your Email SecurityFiltering stops bulk malicious mail. What reaches people is the targeted remainder: a message from a genuine compromised account at a vendor the organization actually uses, a payment change request timed to a real invoice, a mailbox rule quietly forwarding a copy of everything to an outside address.
Those need controls rather than better filtering: multi-factor authentication on mailboxes, alerting on forwarding rules and impossible-travel logins, external sender marking, and a payment verification procedure that does not depend on email confirming email. The last one is a business process and it prevents more loss than any product.
It includes baseline protection. Additional filtering, correct authentication records, identity hardening and training meaningfully reduce risk beyond defaults.
An attacker gains access to or convincingly imitates a legitimate mailbox and uses it to redirect payments or extract information. It often involves no malware at all.
Yes, using encryption options that let recipients read messages securely without complicated software.
Yes, particularly when it is ongoing and paired with technical controls. Neither alone is sufficient.
