Today, securing your emails isn’t as simple as it once was.

As cybercriminals become more sophisticated, businesses need to rethink their security strategies if they want to avoid malware, ransomware, and other dangerous breaches in their industry. The good news is that email safety is evolving with things like SOTI MobiControl for your remote workers to prevent data leaks, cloud-based backups, and 2-factor authentication.

The bad news is that many companies are still relying on old-fashioned solutions like the native Office 365 spam feature to offer all the protection they need. Is it time to upgrade your email security?

Basic Spam Filters Aren’t Enough

Although companies like Microsoft may seem to know what they’re doing when it comes to protecting your emails and business data, it’s worth remembering that it’s up to you to make sure that you have the right security in place for your email and data sharing strategy. Office 365 might be a powerful productivity solution for your team, but it doesn’t necessarily provide the level of protection that today’s email accounts require – particularly when 91% of cyber attacks start with a phishing email.

Companies that want to get ahead of the growing issues with security and privacy in the digital world today need to take a proactive approach to protecting their data. While solutions like Microsoft’s primary spam filter on Office 365 can get rid of some of the dangerous emails that come through to your business, the truth is that it’s not the ultimate method of protecting your emails.

Many modern hacking techniques can still pass through the Office 365 spam and EOP filters, ending up in the inboxes of your critical team members.

How to Invest in Better Email Security

Like most things in the business world, there’s no one-size-fits-all strategy to email security. Finding a safe way to defend your business means evaluating your network and looking for shortcomings in your current security strategy. Here are a few things to keep in mind.

1.      Recognise that Office 365 Only offers Basic Filtering

Office 365 can only offer protection against some basic spam and phishing emails. This means that you don’t get the email security you need to defend against targeted or advanced threats.

For instance, if an attacker links one of your employees to a safe URL, which then sends them through to malware content, the Office 365 spam filter will not notice the second link to dangerous material. This means that malicious content passes through the gateway into your business despite your spam filters.

2.      Introduce New Office Practices

Another point to be aware of when it comes to upgrading your email security is that no software can do everything on behalf of your employees. The people you work with also need to know how to act safely around potentially dangerous messages. Make sure that your team members have the training required to remind them that they should never click on links to unknown websites, or URLs sent by unfamiliar email addresses.

At the same time, ensure that you have a strategy in place to quarantine and remove any potentially dangerous emails before additional information from the content is downloaded onto a personal device or computer. Remember that the Office 365 catch rate is only at 99%. Although this may seem like a high percentage, many other security providers can benchmark at 99.5%. Even this small half of a percentage can make a big difference.

Remember, as of 2018, spam emails accounted for 53.5% of all the messages sent to email addresses online. That means you’re more likely to receive spam than legitimate content.

3.      Introduce Additional Security Measures

Perhaps the best way to make sure that you’re defended in an age where native Office 365 spam filters and email security aren’t enough to protect your business, is to invest in additional sources of protection. Make sure that you have a cloud-based backup system in place in case someone manages to make their way into an employee account and prevent them from accessing valuable data.

At the same time, consider making it harder for attackers to make their way into business accounts by applying two-factor authentication to your crucial accounts. Protecting your emails with 2-factor authentication is easy, and it ensures that if someone manages to get the password and email address for an employee account, they still won’t necessarily be able to access valuable business data.

For mobile device users, Nice Network offers SOTI MobiControl with biometric and two-factor authentication to safeguard valuable data when other forms of security just aren’t enough. This is a crucial part of making sure that you keep your business safe against harmful data leaks.
