Protect sensitive data in motion with Colt Network Encryption services

Effective network security relies on multiple layers of defense, not just at the edge and core of the network but also along the network path. While much of the focus on security is on users and applications, protecting in-flight data as it travels across the network is a critical component of a holistic security strategy. Colt Network Encryption Services ensure secure connectivity, so whichever the network layer you want to secure, we have an end-to-end encryption service to suit your needs.

Network encryption types

Optical encryption

Optical Encryption is available as an integral part of Wave and Private Wave services. Fully transparent to Ethernet, IP and other network protocols, it provides the very highest levels of performance and security in combination.

Always on

Optical Encryption is inherent to the core service, and is embedded in the optical hardware for maximum security and performance.Any traffic that has to traverse the optical backbone becomes encrypted by default, reducing the risk of sensitive traffic leaving the enterprise unprotected, providing always on end-to-end encryption.

Wire speed performance

Operating at Layer 1 of the OSI stack, optical encryption is efficient and scalable. Implemented on the OTN signal layer, the full data payload remains available without latency degradation

Compliance

Colt’s Network Encryption solution offers FIPS-certified AES-256 encryption with standards-based authentication mechanisms such as X.509 digital certificates, enabling operational simplification with seamless integration into enterprise Public Key Infrastructures

Flexible deployment

Customers may choose to manage their own encryption keys or request Colt to do so as an additional service option. Flexibility over the siting of Colt’s optical hardware platforms, including within customer-secured environments, enables the Colt solution to be tailored to the customer’s security policies

Voice encryption

Colt Voice Encryption end-to-end encryption solution that provides additional security for your voice services, including both SIP Signalling encryption and audio encryption.

SIP encryption is offered using SIP Transport Layer Security (TLS) encryption, with mutual authentication, and supports both Asymmetric Encryption (AES) and Triple Data Encryption (3DES)

Colt Audio Encryption secures the audio stream with  SRTP (Secure Real Time Protocol) media encryption, which is a IETF cryptographic protocol used to provide secure communications over an untrusted network. It provides confidentiality and message integrity for media streams.

The expansion in the volume of sensitive information being stored and transmitted by many organisations shows no sign of abating, whilst the Internet and cloud computing present new
challenges. This has led to new risks, whilst data breaches – both accidental and malicious – have grown in frequency, severity and business impact. Security breaches impact network availability, which results in disruption to normal business activity and significant business cost. A loss of customers affects revenues directly and reputational damage can seriously affect the customer retention and growth prospects of a business.

Physically securing networks can be extremely challenging, and even if a rack or room can be secured, data itself must traverse disparate systems and locations. In Europe, the General Data Protection Regulation (GDPR) came into effect in May 2018, requiring all companies that process personal data to comply with its provisions or face stiff penalties in the event of a data breach. And in the US, 47 states now have laws requiring notification of data breaches involving personal information. 29 states have laws that explicitly require entities to destroy, dispose, or make personal information unreadable/ undecipherable. As global regulators increasingly address the pressing need for information security, businesses need to adopt a coherent and holistic strategy across their technology infrastructure.

Colt’s optical encryption solution provides the necessary flexibility to allow customers to implement and comply with specific security policies and requirements. Customers can have secure and exclusive access to the encryption configuration and for management of their encryption keys. The encryption hardware is customer-dedicated, and can be located in the customer’s own secured rack environment to ensure compliance with their broader corporate security strategy.

Why choose a Colt encryption service?

FIPS certified AES-256 encryption with standards-based authentication mechanisms such as X.509 digital certificates.

Encryption is inherent to the service, being embedded in the optical hardware for always-on security and scalability

At Layer 1 of the OSI stack, optical encryption is efficient and guarantees 100% throughput without latency degradation

An embedded optical hardware solution is more scalable and cost effective than one based on multiple external client-level devices

Bandwidth options from 1Gbps to 100Gbps, with support for all major optical presentations including Ethernet, Fibre Channel, OTU2 and OTU4

Colt’s Wave Services provide optical encryption without constraint. They are available across the IQ Network on a metro, national and international basis.

Manage your own encryption keys and configuration according to their own standards

Colt’s optical encryption hardware is dedicated to the customer, and can be located in the customer’s secured environment in order to meet their corporate security policies
