I take issue with this part of the article:<p>> In general, managed tools will give you stronger governance and access controls compared to open source solutions. For businesses dealing with sensitive data that requires a robust security model, commercial solutions may be worth investing in, as they can provide an added layer of reassurance and a stronger audit trail.<p>There are definitely open source solutions capable of managing vast amounts of data securely. The storage group at CERN develops EOS (a distributed filesystem based on the XRootD framework), and CERNBox, which puts a nice web interface on top. See <a href="https://github.com/xrootd/xrootd">https://github.com/xrootd/xrootd</a> and <a href="https://github.com/cern-eos/eos">https://github.com/cern-eos/eos</a> for more information.
