How to choose a security company
Choose a security company on three criteria, in this order: legal operation (operating licence, guards with work licences), supervision you can verify (who checks the guard and how you see it) and stable people with written reporting (who guards your site, who replaces them, what report you get). Price is not a criterion for choosing; it is only a rejection test: reject any offer that cannot show how it covers lawful pay for the hours of cover, because something essential is missing.

How do I check that a security company operates legally?
Ask for the company’s operating licence and the work-licence numbers of the guards it will send. Greek law (Ν. 2518/1997) requires both, so a legitimate company has them ready.
Security companies in Greece operate under Law 2518/1997. A company’s operating licence cannot be transferred, is valid for five years and is renewed only if the original conditions still hold (art. 2 §3) — so check its date, not just that it exists.
- Name and documents: the company must carry the phrase «ιδιωτική επιχείρηση παροχής υπηρεσιών ασφαλείας» (private security services company) in its name and its licence number on its documents (art. 4 §1α). If the offer does not show the number, ask why.
- Each guard’s work licence: security staff must hold a personal work licence, category A or B, valid for five years (art. 3).
- Declared staff: every month the company reports its staff to the police, with each person’s work-licence number and where they work (art. 4). Ask for the numbers of those who will guard your site.
Do not accept “we will send them after signing”. The check happens before the contract, not after. Civil liability insurance is not required by Law 2518/1997 — so agree it explicitly in the contract.
What should I ask at the first meeting?
Ask how your site will be guarded, not what the company does in general: which guard, which hours, who checks them, what happens when they are absent, and what report you receive.
- Who will the guard or team be, and how stable will it be?
- Which supervisor checks the post, and how often?
- If the guard does not show up, how quickly does a replacement arrive?
- What are the written post orders, and who approves them?
- What report do I receive, how often, and what does it contain?
- How is an incident recorded, and how soon do I hear about it?
- How does the offer cover lawful pay for every hour — a 40-hour week, night, Sunday and holiday premiums?
The answers reveal more than any brochure. If an answer is “it has never been needed”, note it: that is where it will be.
How will I know the guard is actually doing the job?
Through evidence you can see yourself, not the company’s assurance: patrols logged per checkpoint, shift reports and an incident log with times and names.
Guarding has a structural problem: it happens when you are not there. So the real question is not “do you have supervisors?” but “what do I see in the morning about last night?”.
- Checkpoint patrols: the guard scans set points, so it shows when they passed where.
- Shift report: what happened, what was observed, what was handed to the next shift.
- Incident log: every incident with its time, description, actions taken and who handled it.
OVIT brings this evidence together in the Guardly platform, so clients see patrols, incidents and reports in the same picture as the operations team.
When is a price a reason to say no?
When it cannot pay lawfully for the hours of cover: every hour of guarding is an hour of one person’s work. A post staffed 24 hours × 7 days is 168 hours a week — more than four full-time guards.
Greece’s Labour Code sets full-time work at 40 hours a week (article 189). So a post covered around the clock needs at least 168 ÷ 40 = 4.2 full-time positions, before leave, sickness and cover are counted.
Price does not tell you which company to choose; it only tells you which one to reject. Ask every offer to show how it covers lawful pay for the hours it takes on. If it cannot, or if it is too low to pay a guard lawfully along with supervision and insurance, reject it: the difference is missing somewhere — usually from the guard.
- The hours of cover, on a 40-hour full-time week per guard.
- Nights (22:00–06:00), with a 25% premium, and Sundays and public holidays, with a 75% premium.
- At least 4.2 full-time positions for every 24/7 post, plus leave and cover.
- The supervision and reporting it promises.
What should a guarding contract say?
The contract should describe what you are buying in measurable terms: posts and hours, replacement time, reports, incident handling, liability and insurance, and how it ends.
- Scope: posts, hours, duties — with the written post orders as an annex.
- Replacement: how quickly an empty post is covered.
- Reports: which ones, how often, in what form.
- Incidents: how and how quickly you are informed.
- Liability and insurance: who is liable for damage during guarding, and a civil liability policy with its amount and cover written into the contract — the law does not require one, so the contract is your protection.
- Personal data: who handles visitor and camera data, if any.
- Ending: notice period and a handover with no gap in cover.
What signs mean I should avoid a company?
Documents that are always late, guards who keep changing and no written reports: any one alone is a reason to ask again; two together are a reason to walk away. A price too low to cover lawful pay for the hours of cover is a reason to walk away on its own.
- The offer is not broken down into hours and posts.
- The operating licence will “come later”, or its number is missing from the offer.
- There are no written post orders.
- The guard changes every week without notice.
- You receive no report unless you ask for one.
At a glance
- Legality first: an operating licence in date (five-year term) and a work-licence number for every guard — before you sign.
- Supervision only counts if you can see it: patrols, shift reports, an incident log.
- Stable people: know who will guard your site and who replaces them when they are absent.
- A 24/7 post is 168 hours a week — at least 4.2 full-time positions on a 40-hour week.
- Price is not a selection criterion, only a rejection test: reject any offer that cannot show how it covers lawful pay for the hours.
- The contract should set out posts, hours, replacement, reports and liability in measurable terms.
Frequently asked questions
How many guards do I need to cover one post around the clock?
A post covered 24 hours × 7 days is 168 hours a week. On a 40-hour full-time week that means at least 4.2 full-time positions, before leave and cover.
Why not simply pick the cheapest offer?
Because price is not a selection criterion. Every hour of guarding is an hour of a person’s work: if an offer cannot cover lawful pay, supervision and insurance, one of them is missing and the offer is rejected. You choose among the offers that pass that test, on legality, supervision, people and reporting.
What should I receive from my security company every day?
A shift report, the patrols per checkpoint, and every incident with its time, actions taken and who handled it.
