Brief Company History

ISECA was launched in the Algarve in mid 2011, and has already provided crime prevention solutions to householders and risk assessments to conferences both in the Algarve and Lisbon.

Brief Personal Background

David Thomas is a resident of Portugal and has some 37 years experience both in international and national policing and security work. Following his retirement as an Assistant Commissioner of Police he has demonstrated success as a security, crime prevention and policing consultant. His clients have included the United Nations Office on Drugs and Crime and INTERPOL. Much of his work has been of a highly confidential nature where integrity, trust and the confidentiality required by clients are paramount


During the last 3 years he has provided security advice to civil government and police in the Algarve as well as various community groups and individual householders. This has included a proposed comprehensive Police/Community Engagement Strategy and Collaboration between the Private Security Alarm Industry and Police in response to Emergencies, submitted to the civil authorities and police.

Unique selling points:

The aim of ISECA is “to promote safer communities, enhance security awareness and reduce the risk of becoming a victim of crime”.

ISECA is both a business and a community organization. In its latter role it helps civil government, police, community groups and others keep the Algarve a safe place to live and visit.  

It is the first and only fully independent crime prevention and security consultancy in the south of Portugal covering the services listed in this profile, independent of any specific alarm companies, suppliers or providers of security equipment. Crime prevention solutions are therefore based solely on identified risks and clients needs.

As a fully independent organization, ISECA aims, and is uniquely placed, to further raise standards in the local crime prevention industry.

ISECA’s business is about identifying risk, comparing this with crime prevention measures already in place and based on the gap, recommending solutions to “minimize risk and maximize safety.”  As a non-aligned organization, clients are assured that they receive professional, fully impartial advice and cost effective solutions. These are contained in a confidential and comprehensive report for the client’s consideration.

ISECA adopts strict, integrity, confidentiality and professional standards which are shown on the website.
