Data Privacy Challenges
Organizations of all sizes rely on IPsec VPNs to prevent snooping and data theft and to
address compliance. IPsec provides a cost-effective and secure way to transfer data over
IP networks.
While IPsec is a mature and well understood technology, new networking paradigms
like cloud computing, as well as escalating bandwidth requirements, are compelling
enterprises and service providers to rethink their VPN strategies. As a result, there is a
requirement to develop VPN architectures that can:
• Support unprecedented IPsec throughput levels privacy with a high-performance IPsec
• Leverage BGP routing for high availability and rapid scaling VPN solution, which is integrated with
• Spin up new IPsec tunnels and gateways on-demand in cloud environments other key security and application
• Minimize power consumption and rack space requirements for data center
delivery components.
• High performance IPsec VPN, traffic
inspection, and stateful firewall
functionality • Encrypt data at unparalleled speeds efficiency
Organizations need a solution they can trust to deliver reliable IPsec connectivity, and one
that can interoperate with their existing routers and IPsec VPN gateways. The Need to Protect Data
Organizations typically transfer sensitive data between remote sites and now increasingly
to public and private clouds. The need to protect data from eavesdropping and hijacking is

such as SSL Insight® and a firewall to protect data center applications.
A10’s IPsec Solution
A10 Thunder CFW includes IPsec encryption capabilities that enable enterprises and
service providers to build out large-scale VPN deployments. By supporting up to 20,000
VPN tunnels per Thunder CFW platform and a broad array of encryption algorithms and
data integrity methods, organizations can deploy Thunder CFW alongside their existing
VPN equipment or build out new VPN networks with Thunder CFW appliances.
The A10 Thunder CFW IPsec solution has achieved the IPsec IKEv2 certification
from ICSA Labs. ICSA Labs testing and certification ensures that A10 Thunder
CFW performs as intended and provides interoperable, cryptographically-based
security services for IP layer environments.
