Thank you for posting @lazariko. Very nice design, great choice of colours, materials...ie.matte background and metallic elements.....as @kyusho has stated, the design reflects security and strength. If one may add a critique...one might say the format of the company name and the logo letters somehow do not compliment each other...it may need a bit of tweaking....nothing major. That being said...it is a security company, therefore it may appreciate the use of a bit of non-congruency.
Thank you for the opportunity to ponder these things.
Congratulations on a logo well done.
