Quintech Mail Defender For Office 365

Updated: Mar 13, 2019

Email is the lifeblood of most companies, but it is also one of the least secure means of communication. As it has become ubiquitous over the years, it has become a carrier for malicious software and web links that can bring down entire enterprises.

Email has quickly become one of the most popular ways for cyber criminals to infiltrate systems and take down networks, possibly compromising confidential details and holding businesses to ransom.

When first invented in 1971, networked email didn’t face the same challenges that it does today. Back then, the internet was barely born, and it was a rarefied space with few participants, mostly from the same military and academic communities. Spam, phishing, and email viruses didn’t exist. Passwords were optional.

Today’s internet landscape is entirely different, with a range of bad actors, including:

State Actors

These are hackers hired and trained by governments to crack overseas systems. Many governments have elite units trained for these purposes, including China’s Unit 613982 and North Korea’s Bureau 1.213.

Criminal Gangs

Often coming from Eastern Europe, these gangs are highly organised, with networks of specialist contractors handling different functions. They run cybercrime like a business.


Often relatively unskilled, hacktivists can organise in packs and target organisations for personal or ideological reasons. They often seek to publicly humiliate their targets.

There are many different ways that businesses can be affected by email attacks:

Social Engineering

Even when their computers are protected by antivirus systems, employees can still be susceptible to manipulation. An email purporting to be from an IT consultant asking for a corporate email account or pretending to be from a CEO’s personal email demanding a list of key customers for a particular department, can unlock valuable company secrets.



A variation on social engineering is phishing. Criminals frequently send mass emails purportedly from financial institutions attempting to get users to log into fake websites with malicious payloads.

Spear Phishing

Spear phishing is a more sophisticated attack, launched after gathering detailed information about a targeted individual and their company. Often accompanied by malicious attachments, it is another attack that can lead to malware infection.

Malware Infection

Typically an effect of an email attack, malware can infect a computer via a link to a malicious website or an infected file. Malware can be the beachhead for an advanced persistent threat, in which attackers can establish a foothold in an organisation's network, and then begin stealing data.

With all of this in mind, it is more important than it ever has been to have a line of defence with emails and this is where Mail Defender comes in. Mail Defender includes an email security service hosted in the cloud.

The service ensures users are protected by continuously improving, comprehensive layers of security encompassing highly accurate spam detection, robust virus defence, and built-in email continuity, to maximise their productive use of email. In modern email protection, one antivirus engine is not enough to secure a system. Cybercriminals regularly test their malware against software provided by multiple antivirus companies. The more antivirus technologies in place to defend the customer, the better.

Although Office 365 does work with multiple antivirus partners, it reserves the right to change them without telling the customer, meaning that you never know quite what protection you’re getting. Mail Defender will provide a robust additional layer of defence.

With all of the above in mind and how important protecting your emails now is, now would be the ideal time to look at a robust security system that will safeguard your business from cyber criminals and allow your business to continue running even when an attack is attempted!

You may think, "Why would a cyber criminal want to attack my business?" This is a common sentence we hear regularly. However, cyber criminals are indiscriminate and more often than not, do not care who they go after as their end goal is to hold any business to ransom and make money from them.
