Security

Every message, inspected at every layer.

Layered AntiSpam & AntiVirus

Reputation, greylisting, RBL/DNSBL, content filtering and multiple AV engines — including Outbreak Protection.

Authentication & encryption

SPF, DKIM and DMARC enforcement, TLS for transport, plus S/MIME and OpenPGP for message encryption.

Access protection

Two-factor authentication, password policies, location screening and outbound throttling against abuse.

Clustering & scale

Distribute the load. Survive any node.

Axigen runs as a distributed cluster: a balancing tier proxies connections to stateless front-end nodes that process mail, backed by replicated storage. Add nodes to scale horizontally — and if one fails, traffic simply routes around it.

Horizontal scale

Add front-end nodes to grow throughput and mailbox capacity without downtime.

High availability

Active-active processing with replicated back-end storage keeps services online through failures.

Cloud-native option

Deploy the same architecture on Kubernetes for elastic, declarative scaling.

AI-assisted email

Smarter inboxes, less busywork.

Axigen brings AI into everyday email — helping users write, triage and stay safe, right inside WebMail.

AI writing assistant

Draft, rephrase, shorten or change the tone of a message in a click — compose faster without leaving the inbox.

Compose · Rephrase

Smart summaries & triage

Long threads condensed to the essentials, with suggested priorities so users act on what matters first.

Summarize · Prioritize

AI-assisted threat spotting

Machine intelligence augments the security pipeline, helping flag phishing and suspicious patterns earlier.
