Addsecure publishes white paper on Martyn’s Law

June 1, 2026

With less than a year to go before Martyn’s Law comes into force in April 2027, European IoT and security provider Addsecure is urging operators of publicly accessible buildings to prepare for the new legal requirements at an early stage. To assist with this, the company has published a white paper explaining the practical implementation of the regulations and providing recommendations for enhancing security in public facilities.
Martyn’s Law was developed in response to the terrorist attack at Manchester Arena and is entering a crucial implementation phase on the ninth anniversary of the attack. The legislation obliges operators of publicly accessible venues to take measures to prepare for terrorist attacks and to have appropriate response plans in place.
The requirements are divided into two categories. Venues with a capacity of between 200 and 799 people fall under the so-called Standard Tier. This includes the creation of security and emergency procedures, staff training and regular reviews of the measures. For venues with more than 800 people, the stricter requirements of the Enhanced Tier apply. These additionally include regular risk assessments as well as physical security measures such as video surveillance, access controls or bag checks.
According to Addsecure, many organisations have so far underestimated the scope of the law. It affects not only large event venues or sports arenas, but also numerous other publicly accessible buildings and facilities.
A key focus of the new regulations is on crisis communication. In future, it will no longer be sufficient to rely solely on traditional fire alarms. Organisations must have both evacuation and lockdown plans in place and support these with reliable communication systems so that security personnel and emergency services can respond flexibly to different threat scenarios.
With this white paper, Addsecure aims to help businesses and public authorities understand the requirements of Martyn’s Law at an early stage and implement appropriate organisational and technical measures. The company believes that timely preparation will be crucial to avoiding legal, financial and reputational risks once the regulations come into force.
