⚠️Latest scams

  • Do not click links, reply, or make any payments.
  • If you didn’t click or reply, your data is safe.

How to spot a scam email, text, message or call

ℹ️Phishing emails try to make you act fast. They can look real, and anyone can be tricked. Protect yourself by following these tips.

  • Never share personal, financial or login details. The University will never ask for your password.
  • Check the sender. University emails about payments or account issues should come from an @herts.ac.uk address — not Gmail, Hotmail, or @herts‑ac.live.
  • Be careful with payments. The University will not send bank details by email. Always use approved payment method.
  • Use strong passwords and turn on two-factor authentication 
  • Take your time. Scammers create false urgency (e.g., “missed deadline”, “outstanding payment”). The University will not pressure you. If unsure, contact the Helpdesk at  helpdesk@herts.ac.uk or Ask Herts.

Email security at Herts

The University uses Mimecast to protect your @herts.ac.uk email from harmful messages, phishing and spam.

How Mimecast protects you:

  • Scans incoming emails for viruses, spam and dangerous links.
  • Holds suspicious emails so they don’t reach your inbox.
  • You’ll get a daily email from postmaster@herts.ac.uk showing any held messages.

Your options for held emails:

  • Release – send this email to your inbox (future emails still held)
  • Permit – send it to your inbox and mark the sender as safe
  • Block – delete it and block the sender

ℹ️ Held messages are deleted after 14 days.

Link protection

  • Mimecast checks links before opening them, so the URL may look different. This is normal.

Attachment protection:

  • Unsafe attachments are blocked. Sometimes a harmful file is replaced with a safe PDF version.

Undeliverable emails:

  • If your email can’t be delivered, you’ll get a Mimecast PostMaster message. This is expected.
