Alarm monitoring, alarm response and keyholding are different services within the security world. Alarm monitoring means a team is scanning for threats 24/7 and will respond by alerting you or the appropriate first responders. Alarm response lets your security service attend the site to check all possible entry and hiding points and prepare a report on that alarm activation. Keyholding takes that one step further and gives your security partner access to the building to complete a full sweep and take any action required.
