Quick Heal Technologies Limited, a leading global provider of cybersecurity solutions, today announced that another of its core cybersecurity innovations has been granted a new patent. With this grant, one more of the company’s technologies is now patented, taking its tally to 8 patents across key markets. Titled “Controlling access to resources based on policies at different layers of a networking model”, the patent has been issued by the Indian Intellectual Property Office as IN590849 B1. The same invention has also been patented in the United States under US Patent No. 12095730, reflecting jurisdiction-specific protection for this technology.
In line with Quick Heal Technologies Limited’s commitment to developing future-ready cybersecurity solutions for enterprises and governments worldwide, this newly granted patent covers a novel method and system for controlling access to digital resources in a zero-trust environment by applying layered access control policies at both higher and lower levels of standard networking models such as OSI and TCP/IP. The invention enables gateway systems to evaluate access requests using application-layer policies first, and then additional network and transport-layer policies, resulting in more efficient, granular, and context-aware security enforcement. It represents yet another invention accomplishment by the R&D team at Quick Heal Technologies Limited in the area of advanced network security.
Commenting on the milestone, Dr. Sanjay Katkar, Joint Managing Director, Quick Heal Technologies Limited, said, “Securing modern digital environments demands intelligent controls that can interpret context at multiple layers of the network stack. With this patent, we are advancing our zero-trust architecture by enabling policies that can simultaneously understand who is accessing, what they are accessing, and how that access is happening across layers. This not only strengthens our enterprise security portfolio but also helps our customers simplify policy management while significantly improving protection against sophisticated attacks.”
The patented technology is designed for deployment in cloud, on-premises, and hybrid infrastructures, where enterprises host critical applications and data across distributed environments. It introduces an intelligent gateway system that intercepts access requests, identifies applicable policies by resource (such as URL or URI), and applies high-level (Layer 7) and lower-level (Layers 3-4 and below) policies in sequence before deciding whether to permit or deny access.
Key capabilities enabled by the patented invention include:
- Multi-layer policy evaluation: Application-layer policies (for example, based on URL, HTTP headers, users, and groups) are applied first, followed by lower-layer policies using IP addresses, ports, and other networking attributes, allowing both broad and granular control.
- Optimized zero-trust enforcement: The gateway operates as a policy-driven control point in a zero-trust architecture, ensuring that each access request is explicitly evaluated and authorized before any resource is exposed.
- Flexible deployment models: The technology can be implemented as a single gateway device, a combination of a network device and a dedicated policy device, or a cluster of policy devices to meet varying performance and reliability requirements.
- Advanced security services: The architecture supports application service chaining, multi-layer load balancing, and honeypot redirection, enabling organizations to integrate intrusion prevention, data loss prevention, and deception technologies into a unified policy-driven framework.
By separating higher-layer and lower-layer policy evaluation and allowing in-memory redirection between different policy-processing stages, the invention helps reduce latency while enabling richer security workflows at scale. This makes it particularly suitable for enterprises operating large cloud-hosted environments, remote branch networks, and distributed hybrid infrastructures.
The new patent adds to Quick Heal Technologies Limited’s growing intellectual property portfolio spanning endpoint, network, and data security technologies, further strengthening its position as an innovation-led cybersecurity player with an evolving global footprint.
