Emails, you interact with them a dozen time a day. You’ve sent and read countless thousands of them, (and ignored way more,) but what about email security?
We don’t want to scare you away from email, it’s an absolutely vital method of communication for any business, which is why it’s worth putting in some thought and action into its security.
Your businesses’ email security can be easily improved, let us explain.
1.) Realtime Link Protection
On a daily basis we all get a lot of emails.
As we’re scanning through our inbox, it’s very easy to click on a link in an email without giving it the proper thought. Do we know the sender? Did we expect a message? Does it look trustworthy?
Realtime link protection provides URL scanning. So when you click a link, it immediately checks the URL before opening the website.
- If the URL you click is included in the database of known malicious sites, the link will not open, and a blocked URL warning opens instead.
- If the URL points to a website that has been determined to be malicious, a malicious website warning page (or a different warning page) opens.
- If the URL points to a downloadable file, and the Apply real-time URL scanning for suspicious links and links that point to files setting is enabled in the policy that applies to the user, the downloadable file is checked.
If all these criteria are deemed safe by the link protection software, the website will open as normal. All in a matter of seconds.
Unlike attachments, which we’ll cover later, internet pages are easily adaptable.
Which means a link that lead to a safe site once, may lead them to a dangerous site later. A link can be checked on the way in, as a part of an inbound email, but might not be checked as it waits in your inbox, even if the content of the link’s destination has changed.
A feature of Realtime Link Protection is ‘time-of-click’ verification of URLs. Which means the link’s destination is consistently checked for malicious activity.
This ensures that when you’re ready to open the link it will be safe, whether you open it straight away, or hours later.
2.) Attachment Sandboxing
Whether it’s an Excel file (.XLS), a Microsoft Word document (.DOC or .DOCX) or a PDF, you likely get a lot of file attachments in your work emails.
They’ll sit in your inbox, just waiting to be opened.
But not all attachments are what they seem to be. Attachments can be forged, and weaponised to install malware to your businesses’ systems.
All from one click.
Attachment sandboxing protects you from these malicious attachments, and best of all it’s automated.
Once you have it set up, every attachment you receive in an email will be isolated, extracted, and placed safely in a virtual protected environment, the ‘sandbox.’
In the sandbox, the attachment can be opened and scanned for any dangerous content or malicious intention. This investigation takes mere minutes.
If it’s safe, it will be released back into your email, just as normal.
However, if malicious content is discovered, the attachment will be quarantined. The user will be notified.
The user still gets their email, but with none of the malicious files.
Imagine it like a bomb squad operation. The suspected item is located, isolated and activated safely. Whether the item is malicious or not, in the sandbox it cannot hurt your systems.
