EXHIBIT 99.1

Magal-S3 RoboGuard® System Receives First Serial Order from Israeli Governmental Customer

RoboGuard® will be exhibited at the Milipol Asia-Pacific Homeland Security exhibition

Yehud, Israel, March 22, 2017– Magal Security Systems Ltd. (NASDAQ: MAGS) today announced that it received its first serial order for its revolutionary RoboGuard® system. The customer, which is an Israeli governmental customer, recently announced the RoboGuard® system to be operational. The announcement followed a series of rigorous ‘in the field’ tests and ongoing inspections, conducted by the customer. The RoboGuard® system is also being evaluated by other governmental agencies for perimeter security of various critical sites.

The RoboGuard system will be presented at the Milipol Asia-Pacific Homeland Security International exhibition to be held in Singapore during 4-6 April 2017.

RoboGuard® is Magal’s revolutionary agile scout robot, which runs along secured fences, ensuring perimeter integrity and is capable of responding promptly to intrusion alerts. It consists of an autonomous unit, traveling on a monorail and carrying several sensors. RoboGuard® has two operating modes: Routine patrol mode, in which it travels autonomously scanning and searching for perimeter anomalies or nearby suspected objects and Response mode, in which RoboGuard® rushes promptly to home in on a suspected intrusion, acting as a first responder. The RoboGuard® provides customers with operational efficiencies by reducing manpower, patrol vehicles and related equipment.

Commented Saar Koursh, CEO of Magal-S3, “We are very pleased with this initial launch order and are proud that our revolutionary RoboGuard® has successfully met the rigorous testing and inspection procedures of our launching customer. We value the selection of RoboGuard® by this particular customer, which serves as a stamp of approval at the highest level for this unique perimeter intrusion deduction system. We see further considerable interest from our customers looking to save manpower cost with our Roboguard® systems.”
