The website of online security professionals CastleCops was shut down over Christmas.


According to a statement on the website, it claims it is ‘currently offline' and states “It has been our pleasure to investigate online crime and volunteer with our virtual family to assist with your computer needs and make the Internet a safer place.


“Unfortunately, all things come to an end. Keep up the good fight folks, for the spirit of this community lies within each of us. We are empowered to improve the safety and security of the internet in our own way.”


Speaking to Dark Reading, founder Paul Laudanski, said: “I believe CastleCops' impact was a great and effective one against online fraud, malware, and spam. CastleCops far surpassed anything I imagined for it, and to that end I, and in fact the community as a whole, are blessed.”


David Harley, director of malware intelligence at ESET, said: “Castlecops have been making considerable efforts to fight crime on the internet in many areas (surviving many an attack from the bad guys in the process) for a long time, but seem to have suspended the service on 23rd December.


Further, Harley said: “What I, and many others, would like to see, is someone finding a way of redeploying the many volunteers who joined forces under the Castlecops banner. Unfortunately, it would take quite an effort to match the six years of hard work Paul and Robin put into the organisation.”
