Enhancing Cybersecurity with Sentinel's Advanced Features

In today's rapidly evolving digital landscape, cybersecurity has become a critical aspect of every organization's operations. With the increasing sophistication of cyber threats, businesses need robust security measures to safeguard their sensitive data and protect their network infrastructure.

All of the connectivity that we provide our customers, regardless of whether it's a solution to get K12 students connected or to allow a physician to remotely monitor and meet with patients at home, runs through our Sentinel platform. From our very beginnings as a provider of devices and connectivity for children, security has been designed and built into our products -- and with every advance in cybersecurity, Sentinel has been updated, too, making it one of the most advanced and most secure managed IoT connectivity platforms available through any carrier, MVNO, or service provider.

Here's a brief overview of some of the layers of cybersecurity that Sentinel provides for our customers.

Data Protection and Private IPSec Tunnels

Kajeet's network protections in Sentinel involve the strategic use of private IPSec (Internet Protocol Security) tunnels in collaboration with the cellular carriers, forming a crucial pillar of its cybersecurity framework. These IPSec tunnels are instrumental in enhancing the security of data transmission for your organization's devices. When your devices connect to the cellular network, Kajeet seamlessly directs the traffic through these dedicated private tunnels, establishing an additional layer of robust protection.

The implementation of IPSec tunnels involves deploying strong encryption protocols to ensure that data remains confidential and tamper-resistant while traveling through the cellular network. By utilizing encryption, Kajeet effectively shields the data from potential eavesdroppers and malicious entities seeking to intercept sensitive information. Consequently, even if the traffic were to be compromised during transit, it would remain indecipherable and unusable to unauthorized parties, effectively preserving the confidentiality and integrity of your organization's data. The significance of these private tunnels becomes evident when considering the potential security risks inherent in data transmission over public networks. Without the protection afforded by IPSec, data packets are vulnerable to interception and exploitation. 

Web Filtering and Access Controls

Sentinel also has a robust web filtering system, a critical component in safeguarding against a myriad of online threats. This sophisticated system employs advanced algorithms and databases to scrutinize website content and categorize them based on potential risk factors. When a user attempts to access a website, Kajeet's web filtering solution swiftly evaluates the site's content against an extensive list of known malicious sites, phishing domains, and harmful online content. This real-time analysis helps identify and block potentially hazardous web destinations, thwarting any attempts by malicious actors to infiltrate your organization's network.

The web filtering system's effectiveness hinges on its ability to rapidly analyze website content and compare it against continually updated threat databases. These databases include blacklists of known dangerous sites and heuristics that can identify suspicious behavior indicative of new and emerging threats. This proactive approach empowers Sentinel to stay ahead of evolving cyber threats, safeguarding your organization from potential zero-day exploits and phishing schemes. It thus acts as a critical barrier between your organization's network and the vast expanse of the internet, providing a secure browsing environment for users.

Moreover, this sophisticated system can be customized to suit your organization's specific security policies, ensuring that it aligns seamlessly with your existing cybersecurity measures and keeps your users safe from unwanted or dangerous content, whether those users are K12 students, doctors utilizing remote patient monitoring solutions, or anyone in between.

Next-Generation Firewall (NGFW)

Sentinel's network protection is anchored by a sophisticated Next-Generation Firewall (NGFW), a cutting-edge solution that outperforms traditional firewalls. This advanced firewall is equipped with deep packet inspection, application awareness, and user identity capabilities, enabling real-time analysis of network traffic at a granular level. Unlike conventional firewalls that solely rely on port and protocol-based inspection, the NGFW can identify specific applications, protocols, and even user actions, making it a robust defense against modern cyber threats.

Deep packet inspection allows the NGFW to scrutinize the content of data packets, not just their source and destination. This level of insight helps detect and prevent cybercriminals' attempts to hide malicious activities within seemingly legitimate network traffic. Additionally, the NGFW's application awareness empowers it to differentiate between various applications and their functions, enabling the implementation of precise security policies tailored to each application's requirements. This level of granularity allows organizations to define access controls based on user roles and security preferences, enhancing overall network security.With these advanced features, Sentinel's NGFW provides unmatched intrusion detection and prevention services, ensuring that your organization's network remains resilient and protected against ever-evolving cyber threats.

Proactive Threat Protection with Intrusion Detection and Prevention

Kajeet's next generation firewall also provides an advanced intrusion detection system (IDS) and intrusion prevention system (IPS). This  proactive approach plays a vital role in safeguarding your organization's network from a wide range of threats.

The IDS component of Kajeet's network protection continuously monitors network traffic for suspicious activities and known threat patterns. When it identifies potential threats, such as unauthorized access attempts or malware activity, it generates alerts for further investigation. Working hand in hand with the IDS, the IPS component takes immediate action to prevent identified threats from compromising your network. By leveraging predefined security policies, the IPS can automatically block malicious traffic or quarantine suspicious devices to prevent further harm.

Addressing Other Cybersecurity Vulnerabilities

Despite all of the advanced cybersecurity layers built into Sentinel, let's be clear: You should never assume that any cybersecurity system is 100% safe. Hackers are smart, they are motivated, they're not concerned with playing by the rules, and they have huge incentives (at very low risk) to find ways around cybersecurity.  That's why, in our prior post on enhancing cybersecurity for your organization, we talked about the importance of keeping up-to-date with the latest software and firmware updates and patches for the devices and software in use by your organization. This is vitally important to understand and to implement as policy, because any cybersecurity scheme is only as strong as its weakest link -- and if the bad guys find an unpatched exploit before the cybersecurity experts do, or if they find a known older exploit on your network that was not properly patched and updated, that exploitable device or software will instantly be the weakest link in your cybersecurity chain. 


In the face of evolving cyber threats, organizations need proactive and comprehensive network protection. Sentinel incorporates a range of cybersecurity concepts into a "defense in depth" paradigm that safeguards your organization's data and infrastructure. By leveraging private IPSec tunnels, web filtering, and a next-gen firewall, Sentinel enhances your network's resilience against cyberthreats. When combined with a program of making sure that devices and software are always properly patched and updated, organizations can ensure that their users and their data are as well-protected as they can be in increasingly challenging digital environments.
