Pépinière d'entreprises _ Atalante Beaulieu

YesWeHack ouvre des bureaux à Rennes et contribue à l’écosystème cybersec en Bretagne

Depuis 2013, YesWeHack n’a cessé de croître et se renforce aujourd’hui avec de nouveaux locaux, au sein de la pépinière numérique à Cesson-Sévigné, en Bretagne, deuxième région « cybersec » après l’Ile-de France.

Le marché de la cybersécurité, particulièrement attractif, attire aussi bien une clientèle nationale qu’internationale. Afin de répondre aux attentes de cette clientèle exigeante, notre équipe s’agrandit et prend ses quartiers à la pépinière numérique à Cesson-Sévigné.

L’équipe YesWeHack bénéficie désormais de locaux dédiés où Romain LECOEUVRE (CTO), Laurent JOUANNIC (Business Development) et Nicolas DIAZ (Communication) auront un accès plus aisé pour coopérer et échanger avec les décideurs et les porteurs de projets bretons.

Qwant has always believed that the development of online services should be done with maximum protection of the confidentiality of users personal data. That is why Qwant took a “privacy by design” and a “data minimization” approach from day one, which requires to think preventively of the technical means and business models that generate as little risks as possible for the privacy of users.

Since 2014, thanks to YesWeHack founders, Qwant has created its bug bounty program.

Each year Qwant offers bounties to the vulnerabilities hunters gathered at La Nuit du Hack, in Paris. Those programs run by HackerzVoice & YesWeHack teams have significantly helped Qwant to build up skills, and to even better protect their users personal data.

And for the 15th edition of La Nuit du Hack, Qwant wants to offer other startups and organizations – thanks to its fund – the opportunity to challenge and increase the security of their services with the best hackers in Europe and in the world, to improve privacy on the Internet.

Qwant grants 10,000 euros to this fund, that will allow to pay bounties to hackers who will discover vulnerabilities on the services of startups or associations that share Qwant’s ethical values.

Organizations that are selected to benefit from this fund will of course be accompanied to put the bug bounty program together.

You can find all the necessary details to apply for this Privacy & Security Fund at the operation’s official website:

The use of Woleet has many benefits:

In constant contact with its community of security researchers, YesWeHack has noted that it is complex for a security researcher and therefore, for a whistle-blower to report security flaws -in a  coordinated way – to impacted organizations. Especially if those organizations do not have a Bug Bounty program registered on !

Vulnerability discoverers often experience difficulties on how to report them to the organizations concerned without disclosing them to a third party and unfortunately direct contact with companies constitutes a legal risk.

A long-time partner of the security research community through its founders, YesWeHack launches

This platform provides the technical means and the required environment for all to adopt the coordinated reporting of vulnerabilities commonly known as “Coordinated Vulnerability Disclosure“.
