Cyber Defender Insights

As organisations adopt hybrid work models, cloud applications, and distributed IT environments, secure remote access has become a critical cybersecurity priority. Traditional Virtual Private Networks (VPNs) have supported remote connectivity for years, but evolving cyber threats and complex access requirements demand a more advanced approach.  This is where ZTNA vs VPN becomes an important consideration for businesses looking to strengthen security while enabling seamless access. Zero Trust Network Access (ZTNA) follows a “never trust, always verify” security model by continuously validating users, devices, and access requests before granting application-level access. Unlike traditional VPNs that provide broad network access, ZTNA limits exposure and reduces security risks. How do ZTNA and VPNs Differ? When a user connects to a VPN, they connect to the corporate network using an encrypted tunnel. After users log in, they gain access to multiple network resources, and compromised c...

As enterprises modernise their security architecture, they face an essential question: ZTNA or VPN? Which remote access security model is suitable to meet the current threat? The emergence of hybrid work has expanded the attack surface, and adversaries are targeting identity, endpoints, and gaps in network trust. Now is a good time for organisations to re-evaluate their legacy VPNs, which cannot provide security at the speed of the changing environment. Why Traditional VPNs Fall Short For a long time now, VPNs have been at the core of remote access solutions; however, these limitations expose organisations to unnecessary risks. Implicit trust model - After the user is authenticated, they are granted access to the entire network, creating a significant opportunity for lateral movement. Performance bottlenecks - By backhauling user traffic through a centralised gateway, the bandwidth consumed on the connection will reduce user productivity. Poor scalability - Legacy VPN architectures ca...

With the rise of remote work, businesses in India are facing new cybersecurity challenges. Traditional VPNs and perimeter-based security models are no longer sufficient to protect sensitive corporate data from cyber threats. This is where Zero Trust Network Access (ZTNA) solutions come into play. ZTNA is a modern security approach that ensures only authorized users and devices can access company networks, reducing the risk of unauthorized breaches. In this blog, we’ll explore what ZTNA solutions are and how they help secure remote access to networks for businesses in India. What Is Zero Trust Network Access (ZTNA)? ZTNA is a cybersecurity framework that follows the principle of "never trust, always verify." Unlike traditional security models that assume users inside the network can be trusted, ZTNA requires continuous authentication and authorization before granting access to applications and data. This ensures that only verified users and devices can connect to business reso...
