How does Network Security work?

With our partners Trend Micro™, we identify and stop attempts to hack into your network and halt files delivered to disrupt your network. The Malicious Websites protection blocks sites known for malicious domains, hacking, ransomware, phishing, and spyware.

Are malicious websites easy to spot?

Not always. Online actors, looking to make a mess of your WiFi and connected devices, are clever and try to trick their way in. A common approach is dressing up their malicious software as downloads you need to watch like a video or read something you've requested. Another tactic is promising to install a legitimate program but installing something else that compromises your WiFi.

If a website is incorrectly being blocked as malicious, you may check it in Trend Micro's Site Safety Center. Enter the URL and check Trend Micro’s safety rating.

What types of malicious websites does Network Security help protect me from?

Malicious websites are sites that attempt to install malware. Malware is a general term for anything that will disrupt your device operations, gather personal information, or gain total access to your devices. Some of the examples are the following:
Type of malicious website
Coin miner
A site that potentially has unwanted scripts or executable files that perform actions related to cryptocurrency, such as coin mining.
Scam site
A scam site defrauds a person or group after first gaining their confidence (used in the classical sense of trust).  It often plays confidence tricks to exploit typical human characteristics, such as greed, dishonesty, vanity, opportunism, lust, compassion, credulity, irresponsibility, desperation, and naivety.
A site that directly or indirectly facilitates the distribution of ransomware.
A fraudulent site that mimics legitimate sites to gather sensitive information, such as usernames and passwords.
A site with downloads that gather and transmit data from computers owned by unsuspecting users.
