Any organization can be a target of threats

Complex targeted attacks and malware are no longer reserved purely for big business. All companies are increasingly tested by the rising levels of sophisticated, malicious emails and social media posts.

External threats come into your business through normal communication channels including email and social media. You need an email security solution that protects your company from all email threats from phishing to malware, spam, and other forms of bad content.

What can you expect from a provider of email security?

Protect your incoming and outgoing email through endpoint protection. In the event of a successful attack, steps for remediation should be put in place. An email security solution should be able to stop malware and non-malware threats such as impostor email (also known as business email compromise). The solution should have filtering capability and business continuity features.

Email filtering provides real-time spam and virus filtering while blocking attacks and monitoring traffic. Messages can be approved or blocked within seconds based on sender, origin IP address, attachment size, file type, or text content. Filtering ensures that trustworthy emails are delivered with minimal delay while suspect messages are blocked or quarantined.

Outgoing email can be automatically encrypted. Email is archived for up to 10 years.

But doesn’t Microsoft Office 365 already include email security?

Microsoft provides only basic email security features, relying on traditional filtering techniques such as IP reputation, volume, and signature based antivirus scans. Unfortunately, the security features available within Office 365 do not provide the advanced security capabilities needed to stop phishing attacks. With Corserva’s solution for email security, data is protected from targeted spear-phishing attacks and zero-day malware. The solution uses advanced machine learning techniques and analysis to protect users from the most cunning attacks. Additionally, the continuity feature of the solution means users will always have access to their email, even if a server fails or unexpected downtime occurs.

Email security should be one part of your recipe for a secure IT infrastructure that includes endpoint security, network security, and SIEM analysis. Corserva has the experience to create the most effective security solutions for our clients. Our email security solutions are comprehensive and include the following components:

Attack blocking & connection protection

When multiple occurrences of harmful traffic is coming from a single server, our solution blocks a wide range of attacks including Directory Harvest Attacks (DHA) and denial of service attacks. Attacks are detected and blocked in real-time and the source IP address is temporarily blocked.

Spam, virus & content filtering

Email filtering can be customized to block and allow email based on sender, recipient, size, content and other factors. Viruses are blocked and users can adjust to what level spam protection is set.

Message quarantine & release

The way suspicious messages are quarantined can be customized so that logs can be kept and quarantined messages can require review before release. Users can review what messages are being flagged as spam and review quarantined messages to make sure legitimate messages are not flagged.
