The Hola browser has also been used for distributed denial of service attacks. Other criticism stemmed from vulnerabilities inherent to the software, which could allow an attacker to deliver malware to Hola users. After Brennan emailed the company, Hola modified its FAQ to include a notice that its users are acting as exit nodes for paid users of Hola's sister service Luminati. This was confirmed by Hola founder Ofer Vilenski who argued that this has always been part of the agreement with Hola's free users when signing up for the service. In late 2014, Hola had begun selling access to its userbase as exit nodes, under the name Luminati, charging $20 per gigabyte for bandwidth that was actually coming from their free VPN users. In May 2015, Hola came under criticism from 8chan founder Fredrick Brennan after the site was reportedly attacked by exploiting the Hola network. That was the second it took off and went up overnight to 40,000 downloads a day', Vilenski told Startup Camel. 'After being around for two months with 80 downloads a day, on January 23, 2013, at 5 PM Israel time, the product was good enough.

Hola Networks Limited launched its network in late 2012, and it became popular in January 2013 when consumers started using Hola for Internet privacy and anonymity by utilizing the P2P routing for IP masking. They started up Hola with $18 million from investors such as DFJ ( Skype, Hotmail), Horizons Ventures ( Li Ka-shing's venture capital fund), Magma Venture Partners ( Waze), Israel's Chief Scientist Fund, and others. This would make the Internet faster for users and cheaper to operate for content distributors. In 2008, Vilenski and Shribman started investigating the idea of re-inventing HTTP by building a peer-to-peer overlay network that would employ peer-to-peer caching to accelerate content distribution and peer-to-peer routing to make the effective bandwidth to target sites much faster.

In 2006, NDS (Cisco) acquired Jungo for $107 million. With the profits from the company, they started Jungo in 2000 to develop an operating system for home gateways. In 1998, Ofer Vilenski and Derry Shribman founded KRFTech, a software development tools company. Paying users can choose to redirect all requests to peers but are themselves never used as peers. Users of the free service share a portion of their idle upload bandwidth to be used for serving cached data to other users.

When a user accesses certain domains that are known to use geo-blocking, the Hola application redirects the request to go through the computers and Internet connections of other users in non-blocked areas, thereby circumventing the blocking. Hola is a freemium web and mobile application which provides a form of VPN service to its users through a peer-to-peer network.
