TCS Earns Prestigious ISO 27001 Certification

ANNAPOLIS, MD, Jul 27 (MARKET WIRE) --
TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a world leader in
highly reliable and secure mobile communication technology, today
announced that it has achieved company-wide ISO 27001 certification, the
highest internationally accepted standard for Information Security
Management Systems (ISMS). TCS is one of only about 300 North American
companies to earn this certification to date.

To meet ISO 27001 standards, a company must show it has a systematic and
ongoing approach to managing sensitive company and customer information.
TCS has implemented the prescribed ISO standards to ensure a secure
environment and work processes that enable it to protect its intellectual
property and assets; meet contractual security obligations; and establish
a robust risk assessment/treatment framework.

The certification is a key indicator of TCS' program to protect vital
customer data from a wide range of cyber threats and vulnerabilities that
can lead to data loss. It provides third-party verification that the
company's ISMS conforms to a standard that helps protect the integrity of
customers' information assets. ISO 27001 certification also gives TCS,
its customers, shareholders and partners added confidence that TCS
subscribes to the best information security practices in the industry.

"This ISO 27001 certification is a reflection of TCS' commitment to the
quality of its information security management system," said Drew Morin,
senior vice president and chief technology officer of TCS. "Successfully
completing the rigorous certification process demonstrates TCS' effort to
safeguard the information assets and intellectual property of our company
and our clients."

Respected in countries worldwide, the International Organization for
Standardization (ISO) develops and publishes standards that establish
best practices across a variety of industries. The ISO 27001 document
provides the latest requirements for an ISMS, helping companies to
proactively identify, manage, and reduce the range of threats to which
information is subjected.

National Quality Assurance, USA, granted the certification after ensuring
that TCS provided a process approach framework to properly allocate
resources, review processes, and improve its management systems, which
ultimately improves the company as a whole.

"TCS' certification was one of the larger and more holistic U.S.
implementations we have seen," said Timothy Woodcome, conformity
assessment director of NQA, USA, one of the largest and most respected
ISO registrars in the world. "Many organizations pursue ISO 27001
certification for a narrow scope of implementation initially, but rarely
for an entire corporation."

To maintain its certification, which is valid for three years, TCS
maintains an ongoing internal audit program, and third-party auditors
conduct annual surveillance audits at all major TCS sites.
