In the past few years, there has been a growing demand for internet access due to the pandemic. It gives more opportunities for hackers to illegally obtain user accounts and hack into the organization's intranets by creating phishing emails or malicious URLs on various topics. Most organizations have a basic understanding of internet security and have security devices deployed, such as firewall or UTM as gateway security, using IPS, anti-virus, anti-spam, Sandstorm, and other functions to defend against external attacks. However, the threat landscape has changed. There is a lot of focus on external network intrusions, but people seem to be ignoring the fact that the number of cyberattacks from within organizations is also increasing, making intranet security the most important issue.

With 480GB SSD and 6 GbE ports, the INF-8400H can handle sudden traffic spikes and provides Quality of Service (QoS) to ensure the stability of intranet services. The INF-8400H is equipped with 1 LAN Bypass module, allowing packets to move straight between LANs and physically bypass the system. A built-in dashboard to increase data visibility, protect important servers from hackers, and adopt Co-Defense with wireless APs to form an integrated wired and wireless intranet security system. Centralized management includes two modes: on-premises CMS clients and ShareTech Eye Cloud, allowing administrators to manage and monitor all devices on a single platform.


When faced with the risk of advanced persistent threats and data breaches, what strategy should the business adopt?



  • All traffic went through the perimeter firewall

  • Network access control

  • Full trust in the intranet

  • VLAN segmentation

  • Increasing number, impact, and complexity of threats

  • Zero Trust model

  • Advanced VLAN segmentation

  • Internal network segmentation to protect valuable assets

  • Increased visibility and detection capability of intranet threats


ShareTech New Solution: Internal Firewall (INF)

An internal firewall integrated with APs, switches, and intelligence analysis to strengthen your intranet security.


Intranet security needs an Internal Firewall

The intranet is the closest part of the network to users, yet it is the least protected. Relying only on gateway security devices would put the entire organization at risk. It is like only the entrance being protected by security, and if any criminal is negligently let in, he may do permanent damage to the entire community. 

As more and more IT security incidents occur in the vulnerable segments within business networks, the previously ignored intranet security must now be re-established based on the Zero Trust model. Deploying gateway firewall is no longer enough, as it cannot effectively filter or block vulnerabilities and threats to the intranet caused by mobile devices, visitors, or with the use of wireless LANs, VPNs, IM applications, and email. Therefore, the network must be reconstructed with a second-layered and segmented defense to reduce the risk of malware spreading across different sections, organizations, and departments.
