When networks were simpler, IT teams relied on firewalls as their primary defense, believing that securing the network perimeter was sufficient. However, as networks have grown in complexity—both horizontally and vertically-traditional security measures are no longer enough. The rise of remote work, cloud computing, layers of devices and applications, both evolved and primitive, and sophisticated cyberthreats has further emphasized the need for a more adaptive security strategy.

Top tips is a weekly column where we highlight what’s trending in the tech world and list ways to explore these trends. This week, we’ll look at how you can shield your privacy when using AI chatbots.

In January 2025, within just a week of its global release, DeepSeek faced a wave of sophisticated cyberattacks. Organizations building open-source AI models and platforms are now rethinking their security strategies as they witness the unfolding consequences of DeepSeek’s vulnerabilities. The attack involved well-organized jailbreaking and DDoS assaults, according to security researchers, revealing just how quickly open platforms can be targeted.

Organizations often struggle to maintain accurate and up-to-date records of user access rights, especially with users and regulatory requirements constantly evolving. This can lead to security vulnerabilities, compliance breaches, and inefficient operations. Are you looking for a hassle-free and structured process to ensure the right users have access to appropriate resources for the required period? Don’t worry, we have got you covered!

Top tips is a weekly column where we highlight what’s trending in the tech world and list ways to explore these trends. This week, we’ll explore a few ways to identify dark data and mitigate the risks it poses. Dark data is a threat to organizations. Despite efforts to prevent it, dark data inevitably makes its way into systems and is often left unaddressed.

In today’s world, cyberthreats are so prevalent that they expose both public and private organizations to data breaches. A single account with excessive privileges is enough for a hacker to infiltrate the entire organization. To protect your organization from such incidents, you can delegate permissions to users based on their roles and responsibilities. This is where role-based access control (RBAC) comes in.

Maintaining network compliance is essential for enterprises to ensure security, operational efficiency, and adherence to industry standards. Failing to comply not only increases the risk of cyberthreats, but can also result in substantial regulatory fines and reputational damage. A strategic approach to network compliance is crucial for protecting your network infrastructure effectively.

Let’s start with the fundamentals: What is Address Resolution Protocol (ARP)? ARP is a vital networking protocol that ensures effective communication between devices on a local-area network (LAN). Its primary function is to map IP addresses to MAC addresses, allowing devices to recognize and communicate with each other within the network. ARP bridges the gap between the logical layer (IP addresses) and the physical layer (MAC addresses).
