Laios is one of the smart guy I know, very hardworking, down to earth and always willing to help. He is an active learner and willing to share his knowledge to other. As a security enthusiast, he has done various industry standard courses and certification and often ranks winners at NetWars or Tournament of Champions. He is a great person, instructor, mentor and recommend to have him mentor / instructor / trainer.

Among those who know Laios in the security community, he is a stand out. Not only does he have an excellent grasp of many advanced concepts, but his passion and dedication put him ahead of many peers. I have seen him persevere on a security issue for days after others have moved on. As a cyber competitor, he is one of the best among his SANS fellows, and often ranks among the winners at NetWars or the Tournament of Champions. What may not be as well known is how dedicated he is to the success of his fellow security professionals. Though more advanced than many, he enjoys investing time and energy to help his colleagues tackle challenges. He would make an excellent addition to any top notch security team.
