Build Multi-Layered Defences Against Cyber Threats

Too many businesses put their trust in a single layer of protection when employing a threat mitigation strategy.  If malware manages to slip past that single thin layer, a company’s IT infrastructure is virtually defenseless, along with their most sensitive business data.

To shield your company in real time against sophisticated and evolving malware attacks, you need additional defences, including a multi-layered cloud email security service.

The first step in building this strong, multi-layered security is to assess your current protection against cyber threats.

Ask yourself these two questions:

  1. Is your cloud security vendor the same as your on-premise (desktop/server) antivirus provider?
  1. Does your cloud email security service feature a layered defence system, with multiple running engines and humans working in unison to block threats?

Combining On-Premise And Cloud Security

For many businesses, their main line of defence against spam containing malware is an on-premise antivirus solution. While this static, one-dimensional defence does offer significant protection, it also requires constant updates to remain effective against evolving cyber threats. Between updates, this single layer is vulnerable to brand-new threats, such as zero-day or fast-break malware.

To truly shut out these threats, best practice is to combine an on-premise antivirus solution and cloud-based email security solution from different security vendors.Using the same vendor for both would likely leave your business vulnerable to unknown viruses.

While some vendors, such as Symantec, offer both on-premise and cloud antivirus security, you are offered better protection by using different vendors and leveraging from the IP of both. If you’re already using Symantec’s desktop or server anti virus protection, for example, look for a separate cloud email security provider to strengthen your defences.

Multilayered Cloud Email Security

In addition to combining on-premise and cloud security systems, for total security, your email security provider should have multiple layers. Many hackers use a company’s email to creep into your network and introduce malware and other cyber-attacks.

The best approach is to choose a cloud email security service that uses multiple engines running in the background to detect spam and malware, as well as people who are constantly monitoring the network for new spam and malware variants. This combination of defences is the most effective approach for identifying new malware threats and quickly blocking them.

In conclusion, a single layer of antivirus protection simply isn’t enough to shield your network and business data from malware, spam and hackers. Multiple layers of protection – including on-premise and cloud email security – are essential to fully protect your business today and into the future.
