Common Threats in O365

Even though O365 has its protection methods for users, it is still possible for certain spam and phishing emails to get through. Evolving tactics, zero-day attacks, polymorphic threats, targeted attacks, and user errors can occur anytime. These can lead to certain spam and phishing emails; in this case, O365 cannot be foolproof.

Phishing Attacks

Phishing attacks are a potential threat to email security as many cyber criminals use different methods to trick you through email to steal your valuable information.

Malware And Ransomware

Hackers use malware and ransomware to gain unauthorised access, which increases the risk of losing valuable data, and even disrupts the system services. They can be a threat to email security.

Business email compromise

Cybercriminals/hackers use business email compromise (a phishing attack) to send unwanted emails to different organisations to steal money and critical information.

Spam And Unwanted Email

You might not be aware of who is sending you spam and unwanted email with a motive. It could expose your critical information and cause data loss.

Data Breaches And Unauthorised Access

Data breaches and unauthorised access can give access to unknown persons, leading to the loss of critical and confidential information.

Client Testimonials: Why Businesses Trust Us

We really loved the products that Topsec provided to us. If I were to pull out a product that we are particularly happy with would-be Phishing campaigns, where it creates awareness among our staff for security issues, promotes awareness, and then Topsec follow that up with training. That’s one of the standout things that Topsec offers.

“The Phishing Training was particularly good. We had one campaign, and we had an extremely poor result. I think 50% of our people, opened and looked at a phishing email. We were very, shocked because it wasn’t particularly an important one. But it was a good one. It gives us an idea of how, they’re coping with unsolicited emails and phishing.

Before we had IronPort in place, and the main reason to let them go was that it was not cost-effective, and it was not providing as much flexibility and management to the spam solution. So, that was the main reason we switched over.”
Andrey Jagotintsev
ICT Manager- St. Michael's Hospital
The culture of response has always been good. We can guarantee that we are going to get a response, sometimes within minutes, which is, which is impressive. If we have a technical issue that we need to discuss with somebody, we always have those levels of support from first-level technicians. If you’re looking for what differentiates Topsec from its competitors that would be the primary differentiation.

How Inbox Protect Works?

The security service for Office 365 users without a Topsec Gateway provides a multi-step approach to protect against email threats. When new emails arrive, Office 365 sends alerts, prompting Inbox Protect to retrieve and pass them through Topsec’s comprehensive security checks. These include virus and spam scanning, sandboxing, and cross-checking against known threats. If a security risk is detected, Inbox Protect directs Office 365 to quarantine the email, removing any malicious content from the user’s inbox. If no risks are found, the mailbox remains unchanged. This layered security process ensures a safer email environment by proactively handling and eliminating threats.
