As business email use and traffic grow, IT organizations must evolve their email security capabilities to counter threats. Layered defenses capable of identifying threats as they arrive, eliminating them in real-time, and remediating any damage they cause are required to protect sensitive email data and business reputation.
Unfortunately, many secure email gateway solutions still need to catch up to modern defenses, relying on outdated authoritarian perimeter-based security practices. Thankfully, a few cloud-native secure email gateways modernize the security stack and significantly reduce deployment complexity.
Detecting Malware
Malware detection is one of the most critical challenges for businesses. If not addressed quickly, it can lead to data breaches, financial loss, and reputational damage.
Using and completing secure email gateway requirements can help mitigate these threats by securing all incoming and outgoing messages, providing custom policies to protect users, and enforcing corporate standards. It also provides real-time metrics of email traffic – down to the individual message level – that allow evaluation of spam and malware trends.
Security vendors often use heuristics and behavioral analysis to identify and reject malicious files delivered via URLs or attachments. Suspicious files are then held in a cloud-based sandbox, allowing the software to inspect them without posing a risk to the organization.
There is a cloud-based solution that employs multiple detection engines, innovative policies, and threat intelligence to help protect against targeted and sophisticated email attacks. It automatically blocks malicious URLs and prohibits the delivery of malicious attachments to internal accounts that have been compromised by phishing emails.
The security stack combines the latest malware protection, heuristics, and content disarm and reconstruction technologies to deliver lightning-fast detection of new threats. Its cloud-native deployment allows you to deploy your solution in minutes without any mail exchanger record (MX) configuration.
Layering email security is a powerful tool that can reduce the impact of email-based cyberattacks on your client’s business and reputation. It combines email security with AI-powered inbox defense, advanced employee training, cloud backup, and automated incident response.
Detecting Spam
Spam is a significant cause of cybersecurity breaches, and finding a solution that will help you catch these messages before they reach your users is essential. Thankfully, several solutions on the market can help you accomplish this task.
One of the most popular email security solutions is an email gateway, a software or hardware device that monitors and filters incoming and outgoing emails to spot threats such as spam, phishing expeditions, and malware. Some gateways do an in-depth analysis of outgoing messages to detect sensitive data – which is essential for protecting against ransomware attacks.
Many different email gateway solutions are on the market, so finding the right one for your organization is essential. Some of these solutions offer free trials or demos so that you can see how they work and decide if they are suitable for your business.
Another crucial part of a multi-layered secure email gateway solution is preventing phishing attempts and business email compromise (BEC). Phishing attacks are the number one threat to organizations, but several other attacks can take advantage of an insecure email account.
With a Multi-Layered Secure Email Gateway solution, your organization can get more protection than what is provided by email providers like Google and Microsoft. It’s also an excellent way to protect your employees and supply chain partners from the dangers of phishing and other email-based attacks.
Detecting Phishing
Email is the most popular and easiest way for cybercriminals to steal personal information from their victims, but it’s not a foolproof solution. The phishing threat is growing, and a Multi-Layered Secure Email Gateway Solution (ESG) can help businesses protect their employees from email-based attacks.
Phishing emails try to entice victims to share personal information by posing as an authorized company or person and asking them to click a link, open an attachment, or reply with sensitive data. These phishing scams can also be used to make fraudulent charges on credit cards or steal identities.
Several types of phishing attacks include general mass-market and spear phishing. Spear phishing involves a specific individual targeted with a fake message from an official source, such as the victim’s boss or someone in the finance department.
Other types of phishing include spam and whaling. These are aimed at high-value targets, like CEOs or board members, and are often accompanied by ransomware malware.
A Multi-Layered Secure Email Gateway Solution provides additional layers of protection to address all phishing threats. For example, a Post-Delivery Protection feature can detect and remove phishing emails from user inboxes that contain URLs poisoned by bots, and Domain-Based Message Authentication, Reporting, and Conformance (DMARC) can ensure emails don’t spoof their domains.
Detecting Ransomware
Ransomware is malware that encrypts files or locks devices, forcing users to pay a ransom to access the encrypted data. The demand may be set within a specific time frame or raised repeatedly.
In either case, victims who do not pay often cannot recover their data. Depending on the type of ransomware, this can lead to a significant loss of business productivity and brand damage.
Detecting ransomware starts with a multi-layered approach to security. This includes a secure email gateway, AI-powered inbox defense, advanced security training, and cloud backup. The solution also combines threat intelligence with progressive incident response and automation to reduce the impact of these threats.
A layered approach to security can prevent ransomware from infecting your network and causing severe harm to your company. It can also protect your data and reputation, reducing an attack’s financial, time, and brand impact.
The most crucial step in detecting and containing ransomware is to isolate the device that has been infected. This will prevent the virus from spreading to other systems and connected drives on your enterprise.
In addition, you should take a broader view of the scope of the attack and isolate all suspicious devices from your network. This will help you regain control over the affected devices and restore critical services before re-enabling communication flows.
