Head of Information Security, Home Credit Bank

I've attended the conference for all five years of its existence. Right before my eyes, PHDays has "grown up" into a serious event that draws major players and visitors from all over the world.

Kevin Williams
General Manager, Team Cymru—UK Internet Security

This was my first time at a conference in Russia, and I liked it. People take a completely different approach to the big questions. I'm already used to hearing everything that Western specialists have to say about security, but here I got a different perspective. Here you can see how private companies, industry organizations, and the government are working together to find a solution to shared problems. It was very interesting.

Sergey Borisov
CSO, RosIntegratsiya

This event is the only one like it in Russia, combining deeply technical talks with topical business presentations by both Russian and international security luminaries.

Anton Karpov
Head of Information Security, Yandex

So many wonderful technical talks and popular topics. The program was great, but the people are what make PHDays shine.

Natalya Kasperskaya
President of the InfoWatch Group

I was blown away by the scale. I expected a large number of people, based on what I read, but it still managed to surpass all my expectations. PHDays is a wonderful place for talking with colleagues and exchanging views among those who research technology and those who write the laws that govern technology.

Alexey Lukatsky
Information security expert

Engaging with colleagues is the reason I come to the forum. In this regard, PHDays is one of the best events in Moscow. Here you can find people you would hardly come across in your daily routine… PHDays brings us together.

Bruce Schneier

The Chief Technology Officer of IBM Resilient, a fellow at Harvard's Berkman Center, and a board member of EFF

We have been organizing security conferences for more than ten years. The major part of them are boring corporate events. However, this conference is something completely different. It not only inspires, it is very practical and quite counter-cultural.


Arkadiy Prokudin

At last our region has a well-deserved event for specialists in information security. I would like to thank, onсe again, the organizers, Positive Technologies.

Team John-users

The Hash Runner contest was fun and challenging, it helped us test some experimental John the Ripper code and identify areas for further improvement.

Marc Furrer
President of ComCom, Swiss telecom regulatory authority

It's a very good experience. PHDays is tremendously creative. It is a fantastic atmosphere. The programme is very versatile—a mixture of unique competitions, interesting conferences, and opportunities to make new acquaintances ... And it's a lot of people. I did not expect that many!

Sergey Khimanych
Head of Information Security Project Implementation, MegaFon

This is the strongest information security event in Russia, period. The organizers make the effort to bring the best experts from Russia and abroad. Many events going on, many interesting talks, and most importantly, many young people. PHDays is the perfect event to help them see the advantages of putting their talents to use for the "light side".

Sébastien Roché
Orange Group

Very impressive. It was a pleasure to see all these great researchers who presented here. Industry stakeholders should definitely come to PHDays to catch up with the latest trends and meet new contacts.

William Hagestad II
Expert in cyber-intelligence and counter-intelligence

PHDays is a unique event where we can see how information security is created and who is who in our field. And it's a place where the binary, digital world of hackers meets the physical world. The forum has realistic contests, such as CTF, Critical Infrastructure Attack, and one in which participants probe for vulnerabilities in a smart home.

Sergei Khodakov
Skolkovo Foundation

PHDays gives talented teams momentum for developing innovations and for finding their way in entrepreneurship, in the white hat community.

Dan Medovnikov
Deputy Editor-in-Chief of the Expert magazine

PHDays has proven it: cyberwar is real, and we are trying to prepare for it, just like all other countries. However, not all threats are taken seriously, at least in business. There are problems on the governmental level also: legislation is failing to keep up with the times. Professionals must declare their initiatives for all to hear.

Stepan Ilyin
Business Development Director, Wallarm

PHDays is one of the best information security events in Europe.

Marc "van Hauser" Heuse

The Hacker's Choice

PHDays is special because of combining hackers and business together.


Alexandr Matrosov

My sincere thanks to the organizers, who moved mountains so that PHDays II could be so successful.

Andrey Prozorov

Only at a conference like this could opposites look so natural together: C-suite suits and tech guys in T-shirts, hackers and defenders, experts and n00bs.

Haythem El Mir

Thus, professionals and students are looking forward to attending again this big event with the confidence that next time it will be even bigger and more attractive.

Alexey Sintsov
Digital Security

It felt like I saw almost all the security big names I know here! That's so important at these events.

Alexander Gorshkov

It was a pleasant surprise to see so many young people participating in such a serious forum. This gives me hope for the future of information security.

Vladimir Styran
BMS Consulting

It's a pleasure to see that interest in PHDays is only growing with each year!

Evgeny Tsarev

The presentations were excellent, plenty of fresh faces, and not too many systems integrators crowding up the place.

Andrey Kostin
Independent expert

Again, thanks to the whole PHDays crew, to the speakers and to the attendees! Hope to see you all there next year as well.

Jerry Gamblin
Missouri House of Representatives

The CTF was also pretty awesome to watch. They had a dumpster diving challenge where the teams had to try to find an MD5 hash. I hadn't seen that before in a CTF and thought it was genius.

Mikhail Emeliyannikov
Emeliyannikov, Popova & Partners

Just listing everything would take more space than I have here.

Vladimir Vorontsov

Digital October, plenty of space, in the center of the city. The milieu and decorations are superb: clean, neat, and gorgeous. Very pleasant spending time in such spaces.

Mersey Shelley
Independent expert, writer

The presentations were exciting, as opposed to the boring marketing spiels we tend to get at Russian security conferences.

Ruslan Permyakov

Positive Hack Days is an event that literally blows up the hacker world.

Vladimir Kochetkov
Positive Technologies

This was simply an incredible event with one-of-a-kind atmosphere, interesting people, and awesome program.

Alexey Komarov

This is among the very best security events I've seen. And definitely the most original one.

Keith Howell

Wonderful location, there were plenty of people and the conference was organized extremely well. The SCADA demonstration was very novel and very unique.

Alexander Sverdlov
Professional security consultant and trainer

The hands-on labs and the infrastructure built for them are incredible.

Marsel Snipl

PHDays is a right place to be and a right place to talk about security.


PHDays is different from any conference I've ever been to. It's incredibly well organized, the program is very technical and the CTF visualization was very cool.

Deviant Ollam

There are a lot of really amazing, smart people here. The more people you put together, the more voices are talking, the more knowledge gets shared.

Babak Javadi

Audience was great, the setup was good. Enjoyable!

Jerry Gamblin
Missouri House of Representatives

I made a great deal of new friends from Russia, the independent nation of Appalachia, and Europe over the last week and will never forget this trip.

Travis Goodspeed

An innovative security researcher

It's this coziness to it that conferences of this size rarely have.


Alexander Bondarenko

I'll say it right out: incredible! This was my first year at PHDays and the two days just flew by.

Arthur Gerkis
Independent expert

Have to point out that this year there were many more speakers from abroad, as well as CTF teams.

DTS Solution
Information security company

The PHDays forum was packed with technical and business seminars, hacking contests and emerging security technologies demonstrating the latest security issues and challenges security professionals face on a daily basis.

Alexey Krasnov

In my lectures this year, I'll be recommending that all students visit PHDays or, if they can't make it to Moscow, PHDays Everywhere in St. Petersburg.

Internet community

The organizers pulled off an unfathomable amount of work to make an event that is truly unforgettable!

Internet community

At PHDays I loved the true hacker atmosphere, interesting talks, and Guinness in the open bar :) All I can add is to thank Positive Technologies for putting the event together. It was awesome.

CTF team

Overall the conference was very well organized, with plenty of exciting contests too, including the (in)famous 2drunk2hack, where one of our engineers finished in second place.

Internet community

PHDays II has raised the bar for atmosphere and comfort at security conferences.

Arvind S Raj

The CTF was cool. It was real fun!

Independent expert

First of all we would like to congratulate PHDays for another great competition and the opportunity to compete against the best password cracking teams worldwide.

Artem Ageyev

My experience confirmed what people were already saying before PHDays this year: it's the biggest and most interesting information security conference in Russia.

Thijs Bosschert
Verizon Business

Participating in the ‪PHDays‬ CTF means a lot of swag!

Internet community

Thank you so much to Positive Technologies for organizing the event so well.
