Q&A with Securitas Korea On-site Supervisor Lim Gyu-nam

At Securitas Korea, security is more than a job—it’s a commitment to people, places, and peace of mind. In this Q&A, we talk with Lim Gyu-nam, an on-site supervisor at a data center, about his journey, his daily work, and what keeps him motivated in the security field.

Q: How did you first join Securitas Korea?

A: After graduating from university, I was looking for a stable job where I could take responsibility and work with people.
I didn’t originally plan to work in security, but I was interested in a role where I could see the impact of my work every day.
That’s how I found Securitas Korea and joined as a security officer at a data center site.

At first, everything was new—procedures, systems, and the importance of the facility.
Over time, I learned more, took on more responsibility, and eventually became an on-site supervisor.

 

Q: What does an on-site supervisor actually do?

A: In simple terms, I make sure the site runs safely and smoothly, 24/7.
My role has three main parts:

  1. Leading the team
    I manage the security officers on site—scheduling, assigning posts, and checking that everyone understands their duties.
    I also listen to the team. If someone is struggling with shifts or a task, I try to find a fair solution. A strong team starts with trust.

  2. Protecting the client’s premises
    This data center is a critical facility.
    We control access, monitor CCTV, check visitor identities, and respond to alarms or unusual situations.
    Every procedure has a purpose, and I make sure we follow them carefully.

  3. Communicating with the client and Securitas
    I’m the bridge between the client and Securitas.
    I report incidents, share daily updates, and discuss improvements with the client.
    Internally, I coordinate with branch and operations managers about staffing, training, and quality.

 

Q: What does a typical day look like for you?

A: No two days are exactly the same, but there is a pattern.

  • Start of shift
    I arrive early, read the handover from the previous shift, and check if there were any incidents or special instructions.
    Then I brief the team: who is at which post, expected visitors or contractors, and any changes in procedures.

  • During the day
    I move around the site, check posts, and support officers when issues come up.
    If there’s a problem with access or a system alert, I help manage the response.
    I also handle reports and logs so that everything is documented.

  • End of shift
    I prepare a clear handover for the next supervisor or team.
    I note what went well, what needs attention, and any ongoing issues.
    This continuity is important for a site that runs 24/7.

 

Q: What are the biggest challenges in your role?

A: There are a few:

  • Balancing client expectations and team well-being
    The client expects high standards and very few mistakes.
    At the same time, my team members are human—they get tired or stressed.
    I have to protect the client’s interests while also looking after my team.

  • Handling incidents calmly
    Most days are routine, but sometimes we face emergencies or unexpected situations.
    In those moments, I need to stay calm, follow procedures, and lead by example.
    Afterwards, we review what happened and look for ways to improve.

  • Keeping up with policies and regulations
    Security work is closely tied to laws, regulations, and company policies.
    Securitas expects us to follow local laws and, in many cases, even higher internal standards.
    I make sure my team understands and applies these rules in daily work.

Some days are tough, but those are also the days when the team grows stronger.

 

Q: What keeps you motivated to stay in this job?

A: Three things:

  1. Responsibility
    I feel proud that our work helps protect critical infrastructure.
    The data center is part of the backbone of modern business, and we help keep it safe.

  2. Teamwork
    I value the relationships with my colleagues.
    We share long shifts, solve problems together, and support each other.
    The site feels like a second workplace family.

  3. Growth
    I started as an officer and became a supervisor.
    I’ve learned leadership, communication, and incident management.
    I see security as a long-term career, not just a temporary job.

 

Q: What would you say to someone thinking about a career at Securitas Korea?

A: I would say:

  • Be ready to take responsibility.
  • Be willing to learn, even when it’s difficult.
  • Respect procedures—they protect you, your team, and the client.
  • Remember that security is about people, not just systems and equipment.

If you care about doing the right thing, staying alert, and helping others, you can build a meaningful career here.

 

Q: How do you see the future of your role?

A: I think technology will play a bigger role, more digital systems, more focus on data protection, and closer integration with the client’s operations.
But even with more technology, people on the ground will still be essential.
Security officers and supervisors are the ones who notice small details, respond in real time, and bring Securitas’ values to life.
