We provide professional and reliable on-site security guards who deliver continuous protection.
At Mountain Security Services Ltd, our SIA-licensed, fully vetted security officers provide a reliable and professional on-site presence that ensures the safety, integrity, and continuity of your operations.
Our manned guarding services are tailored to meet the specific needs of each site we protect—ranging from high-traffic construction sites and industrial estates to corporate offices, residential developments, retail spaces, and more. Each officer is trained to deliver not only physical security but also exceptional situational awareness and customer service.
With a strong emphasis on visibility and vigilance, our guards serve as both a frontline deterrent to unauthorised access and a reassuring presence for your staff, clients, or residents. Duties typically include access control, perimeter patrols, incident logging, health and safety checks, conflict de-escalation, and responding to emergencies—always with professionalism and discretion.
We place great importance on clear communication and integration with your team. Our officers follow detailed assignment instructions, maintain accurate daily occurrence reports, and ensure any incidents or observations are promptly relayed to designated contacts or emergency services.
Every Mountain Security officer undergoes rigorous background checks and holds a valid SIA licence. Many also receive additional site-specific training to ensure they’re fully equipped to represent your brand and uphold your safety standards.
When you choose our manned guarding services, you’re not just hiring security—you’re gaining peace of mind through a dependable, responsive, and highly professional presence on-site.
Routine mobile patrols ensuring rapid response, strong deterrence, and visible protection.
Mobile patrol services are a proactive, cost-effective security solution ideal for sites that don’t require a full-time on-site guard, but still need reliable, visible protection. Our trusted partners conduct scheduled and randomised patrols in clearly marked security vehicles to create a strong deterrent against theft, vandalism, and unauthorised access. Each patrol includes comprehensive site checks, such as inspecting access points, verifying locks, checking for signs of forced entry, and reporting any suspicious activity.
Utilising GPS-tracked vehicles and digital reporting systems to provide our clients with real-time proof of presence, detailed patrol logs, and incident reports—ensuring full transparency and accountability. Patrols are tailored to your specific site needs, whether that includes multiple entry gates, sensitive equipment, or hazardous zones requiring additional checks. The mobile teams are also trained to respond to on-site emergencies, alarms, or unusual conditions, taking immediate action or escalating issues to your designated contacts or emergency services as needed.
With mobile patrolling, you gain the peace of mind that your premises are protected—day or night—with professional oversight, rapid response capability, and a visible security presence. We send a clear message: your site is protected.
Secure key holding and 24/7 rapid alarm response ensuring your premises stay protected.
Mountain Security Services’ trusted partners provide professional 24/7 key holding and rapid alarm response services designed for your safeguard and property. By securely storing your keys off-site, officers are ready to respond quickly and efficiently to any alarm activation—any time of day or night.
When an alarm is triggered, a trained response officer is immediately dispatched to your premises. Upon arrival, they will conduct a thorough inspection of the site to assess the cause of the activation, secure access points, and manage any immediate risks.
Key holding services not only remove the burden and risk from your internal staff but also ensure that every response is handled by trained professionals with the experience to deal with emergencies calmly and effectively.
Expertly trained K9 units providing high-risk site protection and superior deterrence.
With the support of our partners, Mountain Security Services can offer specialist K9 security units—a powerful combination of professionally trained dog handlers and highly disciplined security dogs approved by NASDU. These teams provide an elevated level of protection, making them an ideal choice for large-scale, high-risk, or vulnerable environments where a strong visual and physical deterrent is essential.
Our K9 units are expertly trained in a range of disciplines, including intruder detection, search and tracking, crowd control, and handler protection. The mere presence of a security dog is often enough to discourage criminal activity before it starts, significantly reducing the likelihood of trespassing, vandalism, or theft.
In real-time situations, security dogs can detect movement, scent, and concealed threats far more effectively than human patrols alone. Whether it's a remote industrial site, a construction area, a vacant property, or an event requiring crowd management, K9 teams provide a mobile, alert, and responsive line of defence.
Each handler undergoes rigorous training and operates under strict welfare and safety protocols, ensuring the well-being of both the dogs and the public. They work seamlessly as part of your broader security plan, offering intelligence-led support that enhances patrol operations and emergency responses.
With K9 services, you gain not just a security presence—but a proven deterrent backed by skill, discipline, and reliability.
Professional door supervisors ensuring safety, compliance, and positive experience.
Through our trusted partners, Mountain Security Services provides professional door supervision tailored to maintain a safe, respectful, and welcoming environment across a range of venues — from licensed premises and corporate functions to private events and entertainment venues.
Licensed door supervisors are trained to balance firm security presence with exceptional customer service. They manage access control, verify IDs, diffuse potential conflicts, and ensure compliance with venue policies — all while upholding the dignity and comfort of guests.
We understand that door supervision is often the first point of contact for your visitors. That’s why our teams embody professionalism, discretion, and strong communication skills to represent your brand positively while maintaining order and safety.
Whether it’s managing busy nightlife locations, corporate gatherings, or large-scale public events, our door supervisors provide a dependable line of protection — ensuring smooth operations, secure entry, and peace of mind for both staff and patrons.
Continuous 24/7 surveillance and proactive monitoring to safeguard your premises.
Your Site, Always Watched. Always Protected.
Our trusted partners provide end-to-end CCTV solutions that combine technology, expertise, and rapid response to protect your property, people, and operations through our trusted partners.
This service includes professional installation of high-definition surveillance systems tailored to your site layout and risk profile. Whether it’s a single building, multi-site operation, or large-scale outdoor area, we design and deploy camera networks that deliver optimal visibility and coverage—day or night.
Once installed, real-time CCTV monitoring ensures your premises are continuously observed by trained security personnel. From a dedicated control room, live feeds enable the detection of suspicious activity, alarm verification and response to threats as they emerge. In the event of an incident, swift action is taken to alert emergency services, dispatch mobile response units, or contact key holders as necessary.
CCTV systems also support secure footage recording and storage, enabling detailed post-incident analysis and documentation for insurance, legal, or internal review purposes. Regular system maintenance and health checks are included to ensure consistent performance, uptime, and image quality.
By integrating CCTV into your broader security strategy, we provide an intelligent, visible deterrent that not only helps prevent crime but also enhances safety, accountability, and operational oversight.
