Berezha Security Group vs Tallium: overview
Berezha Security Group
Three established Ukrainian cybersecurity professionals founded Berezha Security Group in Kyiv in 2014, and unlike nearly every other company on this list, it doesn't build general business software at all: its work is penetration testing, red-team engagements, and security consulting. That narrow focus is exactly what makes it valuable to buyers who specifically need a security audit or offensive-security engagement rather than a development partner, and it is simply the wrong vendor for anyone looking to outsource product development itself.
Tallium
A published hourly rate is what sets Tallium apart on this list: $25-$49 per hour per GoodFirms, backed by a 5.0-star rating across more than 40 verified reviews, out of a company founded in Kyiv in 2012. That published rate is unusual among the companies reviewed here, most of which don't disclose pricing publicly, and it makes Tallium a genuine cost-transparency option for smaller buyers. Its boutique scale suits single-team engagements better than very large, multi-team enterprise programs.
