Software vulnerabilities, also known by the IT cybersecurity community as bugs, security flaws, errors in code, and software weaknesses have been in the spotlight recently. In fact, software weaknesses, in general, have been a hot topic in 2021, in addition to ransomware. Corporate software exploits are popular amongst cybercriminals, as there is more profit to be had this way.

When it comes to network equipment and enterprise gear, given that they are the first defense wall between incoming network traffic and the operating system, it is crucial to patch any vulnerabilities as quickly as possible to avoid any exploits leading to malicious actors breaking in. Especially because a lot of machines can be linked to this hardware equipment, security issues put them and the users at direct risk of malicious actors.


NETGEAR is a multi-billion dollar computer networking company established in 1996, that operates multi-nationally. NETGEAR’s products and solutions are sold in an estimated 24,000 retail locations worldwide.
