Email Protection Services
Email is where most attacks on small businesses begin. Vulcan Telecom protects your email with spam and phishing filtering, quarantine, encryption for sensitive messages, sender authentication and simple training for your staff.

The inbox is the front line
A fake invoice, a “your mailbox is full” link, a message that looks like it came from the boss asking for gift cards – these reach small businesses every day. One click can hand over a password or install ransomware. Email protection catches most of them before they arrive and helps your people recognize the rest.
How we protect your email
- Spam and phishing filtering – messages are checked for known threats, fake senders, dangerous links and attachments before they reach the inbox.
- Quarantine – suspicious messages are held aside instead of deleted, so a real email caught by mistake can be released.
- Link and attachment checks – links are checked when clicked and attachments opened safely first.
- Encryption – send sensitive information, such as financial or medical details, so only the recipient can read it.
- Sender authentication – SPF, DKIM and DMARC records for your domain make it much harder for criminals to send email pretending to be you, and help your real email reach inboxes.
Settings that matter in Microsoft 365
Many protections are already in Microsoft 365 but not switched on. We review the security settings, block automatic forwarding to outside addresses (a favorite trick after an account takeover) and make sure multi-factor sign-in protects every mailbox.
Training your team
Filters catch most of it, not all of it. A short session with your staff – how to spot a fake sender, why to confirm payment changes by phone, what to do after a wrong click – turns them into the last line of defense. Law firms, read 5 signs your email is a security liability.

FAQ
Email Protection questions
Isn't Microsoft 365 filtering enough?
It is a good base, but many settings are off by default. We switch on and tune what matters, and add more filtering where it is needed.
Why are our emails landing in customers' spam?
Often because SPF, DKIM and DMARC records are missing or wrong. We fix the DNS records for your domain.
