Link Lock Cyber Security Feature and FAQs

Penta’s Link Lock security feature adds security to protect you from malicious or potentially risky links that are sent through email. We are making this feature available to our Penta-hosted email clients for free.

How does it work?

Link Lock rewrites all the links in every inbound email thereby sending the destination link through a database that checks if it has been blacklisted. When a link is clicked, our system verifies if the destination URL has been previously flagged as dangerous. If the link has been flagged, the user is presented with a block page indicating that there is a security risk.

Link Lock cannot detect all malicious links so it is important that you remain careful of phishing attempts and not click on links from unknown and suspicious senders or when being asked for sensitive information like passwords or payment details.

What’s the impact of this feature?

Since all links in inbound emails will be rewritten by Link Lock, if you hover or click on a link, you will notice that the destination URL starts with https://linklock.titanhq.com/

Will I still be able to visit a blocked URL?

We have disabled the option to continue to visit a blocked URL for your security. We can enable it on your request, but we recommend keeping it in place in order to keep your IT environment secure.

Can I disable this feature altogether?

We can disable it on your request, but we recommend keeping it in place in order to keep your IT environment secure.

What if a link is reported malicious but it isn’t?

You can easily get in touch with our Service Desk through any of the available channels to request whitelisting of specific links and domains that you trust. Email support@penta.ch.

What action do I need to take?

No action is required from your side. We will be rolling out this feature on our servers in the next few weeks and the process will take place seamlessly.

Is there any cost associated?

There is no cost on you for this feature. We are making this feature available to Penta on-premise email clients for free.

What is phishing?

Phishing is the fraudulent practice of sending emails purporting to be from reputable companies in order to induce individuals to reveal personal information, such as passwords and credit card numbers. Here are a few resources by Penta that can help you understand phishing:
