IPsec Security Gateway
Fortify your AI vision and digital transformation with IPsec
Elevate your network to the forefront of today’s secure and trusted digital landscape with the Nokia IPsec solution—a quantum-safe, resilient, high-performance security solution built for artificial intelligence (AI) workloads, massive data volumes and emerging quantum threats.
Why do IP networks need better security?
Networks and data have never been at greater risk. Most of the world’s content and economies are becoming digitalized, which means that corporate, government and personal data traverses public and private networks in ever-increasing volumes.
The rise of the Quantum 2.0 era and the rapid expansion of AI are reshaping the cyber threat landscape and creating new security challenges. Quantum computers put widely used historic cryptographic technologies at risk, while AI-driven, distributed infrastructures increase the exposure of massive data volumes as they traverse our public and private networks.
To protect the confidentiality and integrity of sensitive “data in flight,” organizations of all sizes must adopt secure, trusted IP network solutions that safeguard their digital transformation and AI investments.

Why is IPsec critical for IP network security?
Internet Protocol Security (IPsec) is a robust, battle-tested protocol suite that's been protecting internet connections for decades. It’s evolving to meet the demands of today's hyper-connected landscape.
Defined by the Internet Engineering Task Force (IETF), IPsec is a suite of protocols for securing IP communications at the network layer (layer 3 of the OSI model). It works by authenticating and encrypting IP packets and doesn’t require modifications to higher-layer applications. Unlike application-layer security (e.g., TLS), IPsec provides end-to-end protection for any IP-based traffic.
Whether securing global VPNs for a remote workforce, shielding sensitive transactions across cloud platforms, protecting site-to-site network connections or locking down IoT ecosystems, IPsec delivers seamless, application-agnostic protection that ensures the confidentiality, integrity and authenticity of the data.
What is driving IPsec deployments?
IPsec’s market momentum is propelled by a confluence of global trends and urgent needs:
Escalating cyber threats
With around 2,200 attacks occurring daily worldwide, businesses are prioritizing defenses against ransomware, Advanced Persistent Threats (APTs) and zero-days. Many are adopting IPsec as a proven shield.
Digital transformation and cloud expansion
The shift to hybrid work, multi-cloud environments and remote access demands secure and trusted connectivity. IPsec meets these demands enabling zero-trust models that are accelerating growth in sectors such as IT and telecom.
Regulatory imperatives
Stricter regulatory directives and data privacy laws (e.g., CCPA, GDPR, HIPAA, NIS2) mandate encrypted communications, creating compliance-driven network operations. IPsec helps fulfill these mandates with strong and flexible encryption.
IoT, 5G and edge computing
Billions of devices connect via 5G networks, where device-to-cloud communication must be authenticated and encrypted. This is driving demand for IPsec into fast-growing markets such as smart cities and industrial IoT.
Technological advancements
Innovations in quantum computing- and AI-enabled cyber threats enhance IPsec's appeal because it can address current and future risks for telecommunication, AI and cloud provides along with mission critical enterprises.
In essence, IPsec's market trajectory reflects its evolution from a foundational protocol to a cornerstone of secure and trusted network infrastructures.
