What is endpoint security?

Anton P. | June 8, 2020

Endpoint security is a practice of protecting computing devices that are vulnerable to cyber attacks or other malicious acts. Today, threats are continuously increasing along with the growing number of IoT devices, otherwise known as endpoints. Cybercriminals scout the ever-changing endpoint landscape and adapt their techniques. Hence, endpoint security could be the answer if you want to prevent access attempts and other attacks on your organization.

What is endpoint security?

In order to learn what endpoint security is, several sub-questions are equally important. For instance, what is the endpoint exactly? Why do endpoints need protection in the first place?

Generally, an endpoint is a device connected to a particular network. These can include laptops, tablets, mobile devices, printers, and all other gadgets that communicate with systems remotely. Every endpoint is a potential target for threat actors because they are the weakest links in the whole network.

In these ever-evolving digital times, the number of new endpoints is increasing rapidly. Reportedly, 127 devices connect to the internet each second. It’s more than smartphones and laptops – think about all the wearable watches, voice-control assistants, or network-connected sensors in our cars. As the range of devices continues to evolve, endpoint security solutions also need to adapt progressively.

Many enterprises adopt practices such as bring-your-own-device (BYOD) or working remotely. Although such methods may be convenient and less expensive, they also create multiple endpoint threats. Employees who use personal devices, work from home, or connect to public Wi-Fi are perfect targets for attackers to infiltrate corporate networks. Therefore, without proper endpoint security measures in place, businesses risk it all.

How does endpoint security work?

Most endpoint security solutions consist of two core components – data encryption and application control or user management. The encryption fully encodes sensitive data. Application control prevents users from downloading dangerous software that could lead to unauthorized network access.

Endpoint security solutions are available for both enterprises and individual users. Of course, the primary targets are large organizations that own more endpoints and valuable data. Hence, enterprises use sophisticated endpoint protection solutions and dedicated security platforms to keep the whole network airtight.

However, individual consumers can benefit from deploying endpoint security tools as well. Without any online defense, you leave yourself open to data theft, malware intrusion, or other attacks. Luckily, you can use more straightforward – yet effective – security technologies.

Antivirus software

Viruses, spyware, and other malicious software bombardment is a continuous battle – more than 60,000 new pieces of malware emerge each day. However, an up-to-date antivirus software protects you from it all, including Trojans, zero-day exploits, worms, and ransomware. Antivirus software is central to endpoint security. It scans your device to locate malicious applications that could create network vulnerabilities.

A VPN (Virtual Private Network)

Staying secure goes beyond antivirus software. Since one of the critical endpoint security components is encryption, VPN does precisely that. It scrambles your online data to an indecipherable format, making it completely private. Much like an antivirus program protects your device from malware, a VPN shields your internet traffic from snoopers. With military-grade VPN, such as Atlas VPN, you get robust protection to your endpoints, nearly impossible to break.
