Optus has attained global security standard certification at its Sydney data centre which provides a range of hosted services.

The telco has attained ISO 27001 Information Security Management System (ISMS) certification for Expan co-location services at its Ultimo data centre in Sydney.

The certification, ISO 2700, is a globally recognised standard governing security of information and network systems.

Optus' accreditation follows a thorough assessment of its hosting services including the identification and implementation of rigorous controls to meet the information security needs of its corporate and government customers.

Optus business marketing director, Marilyn Conyer, said information security is critical to the sustained success of today's enterprises.

As a result, she said organisations demand assurance that their valuable information assets are protected against unsolicited intrusion.

Operating within a secure environment, the Optus data centre provides 24x7 hosting and networking solutions, coupled with Optus IP-VPN, Ethernet and Internet services, providing a single point of accountability.

The hosting services are fully scalable, offering high-speed Internet access via an Ethernet port, with a variety of bandwidth options.

With half-yearly surveillance audits, ISO 27001 eliminates the need for costly multiple customer and partner security assessments, while ensuring ongoing technical and implementation compliance.

"With their reputation on the line, organisations expect the highest levels of security and accountability from their co-location partner," she said.

"ISMS certification provides that extra layer of protection, while regular audits of our information security systems ensure continuous improvement in our ability to combat security threats."
