Protection
MTD vs MDR: what's the difference, and which do you need?
One protects your devices in real time. The other puts human analysts behind your accounts. Here's how to choose — or why you might want both.

Most people buy security software and assume the job is done. In practice, protection has two halves: the software that blocks bad things on your device, and the people who notice when something slips past it.
Mobile Threat Defense (MTD) is the first half. Managed Detection and Response (MDR) is the second. They solve different problems, and understanding the split makes it much easier to decide what to pay for.
What MTD actually does
MTD runs on the phone, tablet or laptop you use every day. It inspects the links you tap, the apps you install, the networks you join and the configuration profiles that quietly change how your device behaves.
- —Blocks phishing links before the page loads
- —Flags apps that request unreasonable access
- —Warns you on hostile or spoofed Wi-Fi networks
- —Filters DNS so malicious domains never resolve
What MDR adds
MDR is human. Analysts monitor signals from your accounts, credentials and identity data around the clock, investigate what looks wrong, and act — including helping you recover when an account is taken over.
Software is excellent at known threats. People are better at the strange, slow, targeted attacks that don't match a signature.
So which one?
If your risk is mostly everyday — scam texts, dodgy links, public Wi-Fi — MTD alone covers a lot of ground. If your email is the key to your financial life, or you've already been breached once, MDR is the layer that matters.
Together they cover both the device and the identity behind it, which is why most members eventually move to the combined membership.

Why your email address is the real target
Attackers rarely want your inbox. They want the password resets it unlocks. A secured personal mailbox changes the maths.
Seven signs a message is a scam
Modern phishing is well written and well designed. These are the patterns that still give it away.
Protecting a household, not just a person
Attackers target the least protected person in a home and work inwards. Household thinking closes that gap.
