Email protection with proxies

A large number of emails that reach every company’s email servers contain malicious URLs or malware attachments. Non-malware threats, such as phishing attempts, also pose a big risk. To prevent confidential information from falling into the wrong hands, cybersecurity companies offer email protection solutions that utilize proxies to protect sensitive communication. In this blog post, learn all about how proxies can be leveraged to increase business communication security.

Proxies, one of the underlying technologies that these tools are based on, make it possible to scan and filter emails efficiently and without tipping off the attackers.

How do proxies help protect email communication?

Often defined as a secure gateway or an intermediary connection, a proxy server helps establish a layer of extra security while shielding away the original IP address and thereby increasing the overall security of an internet connection.

Located between a client and the rest of the internet, one of the important functionalities of a proxy server is to verify and forward incoming requests to the clients. A proxy server will evaluate and filter every single IP request made by the client and IP responses received from the internet. 

With several recent findings highlighting the fact that an average data breach faced by an organization takes at least six months to be detected, the urgency and applications of a reliable proxy server becomes increasingly apparent. From protecting your organization’s business email to improving the overall security quotient of your IT resources, below are the few advantages of online proxy. Read on.

The significance of email protection

As business organizations across the world have grown increasingly dependent on email communication, effective measures must be taken to steer clear of email-related cybersecurity attacks such as eavesdropping and phishing attacks.

Business organizations tend to share sensitive information across emails, meaning that an eavesdropping attack can be a devastating blow and compromise the overall network security of an organization. In the first half of 2019 alone, more than four billion records have been exposed as a result of data breaches. An email proxy can certainly help secure business communication and shield business communications from outside intrusion.

What kind of proxies work best for email protection?

Recommendations: Datacenter Proxies Residential Proxies

Both datacenter and residential proxies work great for email protection. Datacenter proxies are best for basic email filtering while residential proxies enable smarter features, such as checking potentially malicious links via a large number of real IPs.

This strategy makes it nearly impossible for the attacker to identify and counter the protective measures.

There are multiple other benefits that proxies offer in the context of business security. Let’s take a look at some of them.

Limiting internet footprint

A proxy acts as a buffer between your computer and the rest of the internet while concealing your private IP address and exposing its public IP address instead. By doing so, a proxy server limits the internet footprint, making it harder for attackers to snoop through the network and gain access to sensitive data.

Business organizations conducting research and development work greatly benefit from the anonymity provided by the proxy servers. Moreover, attackers trying to steal the sensitive and proprietary development work will be thwarted from gaining access by the extra layer of tunneling provided by the proxy server. 

Using proxies to protect against DDOS attacks

A DDoS attack can be a devastating blow to a company’s IT infrastructure, resulting in down time or significant slowing of company’s website loading speed.

According to recent security surveys, an average DDoS attack might cost an organization anywhere between $20,000-$40,000 per hour, making it an expensive ordeal. When combined with other cybersecurity measures such as distributed cloud data storage and peering, proxies can help forestall potential DDoS attacks and spare your organization from loss of time and revenue.

While storing data across multiple servers helps distribute data and control overwhelming your company website’s web server, peering equips the network to handle a greater amount of traffic effectively, and the proxy server distributes the incoming traffic across several web servers, facilitating a smooth flow of web requests and massively decreased chances of a DDoS attack. 

Improving internet speed

Contrary to the common belief, deploying proxies do not slow down the internet speed. They simply enhance the bandwidth allocation, resulting in an improved internet speed. Proxy servers can be used to cache all the web pages and files that are commonly accessed by the employees of an organization, which offers two main benefits:

  1. Faster loading times,
  2. less data consumption.

Moreover, proxy servers can also be used to block ads and restrict malicious websites for creating a more seamless and secure browsing environment.

Wrapping up

While no amount of cybersecurity measures might offer a one-hundred percent protection against cyberattacks, investing in preventive security measures can help secure your organization’s business email and other sensitive data.

You can register right away to get access to residential and datacenter proxies to start implementing preventive measures right away, or book a call with our sales team if you have any questions on how proxies might aid in email protection.
