Sentinela Serviços de Proteção

Website for a company that provides concierge, access control and monitoring for residential buildings, wholesalers, hospitals and factories. A sober look in black and military green that conveys discipline and leads building and facility managers to request a proposal.

01 · The challenge

Selling trust before selling the service.

Whoever hires concierge and security is handing over access to their building or company to another team. The website had to show who is behind Sentinela, prove there is a method and make clear the service follows the law, before asking for contact.

02 · The solution

A website that looks like a serious operation, from top to bottom.

Real photos of the team and the control room, a dark palette with military green and direct copy. The page introduces the founder and his background, the three services, the reasons to choose the company and the five-step process, with proposal requests and WhatsApp at the start and at the end.

03 · Structure

From credibility to proposal request.

Each block answers a question from someone about to hire security: who they are, what they do, why trust them and how they work.
