    Qostodian: easy to use and quick to set up

    Reviewed on May 26, 2026
    Review provided by G2
    What do you like best about the product?
    The platform works well: the zero-copy is solid and the UDSI feature is really powerful. Pankaj is technically very competent, and the TAM model (Pankaj + Alexandre) provides a real advantage on the contractual level.
    What do you dislike about the product?
    API keys, OAuth tokens, webhooks: nothing is available out-of-the-box. You have to go through UDSI; it's doable, but it adds complexity. (Specific gap in the TELUS environment.)
    What problems is the product solving and how is that benefiting you?
    Today, TELUS discovers that there was a problem after a breach. Qostodian allows seeing the risk beforehand — who are the 50 users most at risk, which files should be deleted, where credentials are stored in plain text. With the deployment of Gemini and other AI tools at TELUS, sensitive data can end up in prompts or files accessible by these tools. Qostodian provides the necessary visibility layer to deploy AI responsibly.

    Discover Unknown Sensitive Data with Qostodian's Effective Solutions

    Reviewed on Apr 29, 2025
    Review provided by G2
    What do you like best about the product?
    Qostodian has been a great tool for helping us find sensitive data across a bunch of different sources (OneDrive, Sharepoint, Workstation, FileShare). It's fast, easy to use, and allowed us to discover sensitive data that we didn't know we had. We had a lot of false positives at first but most of them have all been fixed by their new improvements.
    What do you dislike about the product?
    At first, there were a lot of false positives, which made it harder to trust the results. A lot of it was because our internal data looked similar to sensitive pattern. The good thing is they've fixed a lot of it with updates, but some fine-tuning is still needed depending on your setup. They helped us to solve this problem.
    What problems is the product solving and how is that benefiting you?
    Qostodian helps us ensure that only authorized individuals have access to sensitive information and that this data complies with the latest regulations in our region.

    Powerful Tool to reduce privacy organization risk

    Reviewed on Apr 17, 2025
    Review provided by G2
    What do you like best about the product?
    The tool is able to quickly give deep insights on the privacy information residing within the organization, by reporting and alerting. It is easy to focus on high risk sources or individuals, so the results come quickly.
    What do you dislike about the product?
    Access to raw data information is tricky
    What problems is the product solving and how is that benefiting you?
    Before the implementation of Qostodian, we always looked at trying to classify the information we had on a file level, but with Qostodian we are able to tackle it at the information level, so it give a more comprehensive reporting and it's easier to take action on specific type of information and it doesn't rely on classification. It's able to shed some light on forgotten places or broken processes.

    Data Security Made Simple

    Reviewed on Oct 22, 2024
    Review provided by G2
    What do you like best about the product?
    I like the face that the agent allows me to scan all data on a workstation and server and catagorse the information and put it in a easy to understand output to allow for easy reporting
    What do you dislike about the product?
    I am not a fan that it also shows information that isn't needed as it will rank information that matches it criteria but will display this in the portal i think if the score is below 0.6 certain then the information isn't needed to be put into the report
    What problems is the product solving and how is that benefiting you?
    We are a large organisation and Data security is at the forefront for us so with Qohash we are now able to scan for sensitive data that is on the users computer and should be on the file shares, this benifits us as it allows us to make the workstation secure and we are confident that the data is secured

    Powerful tool for risky data analysis

    Reviewed on Sep 24, 2024
    Review provided by G2
    What do you like best about the product?
    Very good at finding confidential data, and showing where and what was found. It found files and directories on our fileserver people had forgotten about for years, that contained credit card numbers in plain text, and automatically sorts the findings into departments straight from your AD. It is overall fairly easy to use, and their support team was outstanding at getting all the inititial configurations set up. It integrates with user devices, network drives, and Office 365 (email, sharepoint, etc.).
    What do you dislike about the product?
    The reporting options are still 'a work in progress'. There no good way to quickly summarize the findings for management.
    What problems is the product solving and how is that benefiting you?
    The product is highly effective at finding and clearly displaying confidential data found on user's devices, network drives, and Office 365. Data that in some cases has just been sitting there on old drives for years, completely forgotten but still accessible if an attacker were to get in and find it. This will greatly aid us in reducing risk and data loss in the event of a data breech.

    Great tool backed by an amazing team

    Review provided by G2
    What do you like best about the product?
    I’ve had the pleasure of implementing Qostodian Data Security Posture Management with my team, and I must say, it has exceeded all my expectations. The team behind this tool is outstanding and incredibly agile. They are always ready to adapt and respond to any challenges that arise, ensuring a seamless experience for their users.

    The tool itself is remarkably intuitive and easy to deploy. From the moment we integrated it into our system, it has been smooth sailing. One of the most impressive aspects is that it has no impact on our production performance due to its low ressources requirements, which is crucial for maintaining our operational efficiency.

    Moreover, the support team takes every case seriously and goes above and beyond to resolve any issues. Their proactive approach and dedication to customer satisfaction are truly commendable. Overall, Qostodian Data Security Posture Management is a top-notch solution for anyone looking to enhance their data security posture without compromising on anything.
    What do you dislike about the product?
    One area for improvement is the current lack of integration with external syslog systems. Adding this feature would greatly enhance our ability to manage cases that need to be handled by our SOC. However, I’m pleased to share that this enhancement has already been added to our roadmap during our recent QBR. This proactive step demonstrates the team’s commitment to continuous improvement and responsiveness to user feedback.
    What problems is the product solving and how is that benefiting you?
    The tool help to identify the security risk of our endpoints and provides a score that helps to evaluate the evolution of the security posture of our organisation.

    Excellent product with great support team

    Reviewed on Aug 22, 2024
    Review provided by G2
    What do you like best about the product?
    Using both their Recon and Prime solutions and both work great. Scans are lightweight, no performance issues noticed in either our cloud tenant, workstations, or servers. Product support team is great and very responsive and they are continually adding features/improvements as the development goes on. Installation and configuration was pretty straight forward for both platforms and didn't require significant changes to any of our environments. Workstation agents were easily able to be pushed via our MDM.
    What do you dislike about the product?
    Some automation was missing at deployment (automated scans/datastore detection) but most of those have been implemented over the last few releases. Occasionally there's some bugs but understandable with a new product and support is always quick to acknowledge and plan fixes in releases.
    What problems is the product solving and how is that benefiting you?
    Easily detecint and identifing sensitive information on our user's workstations, cloud accounts, and file servers. Massive time savings and easy compliance management.

    What do you like best about the product?
    The initial installation and preliminary tests went pretty smoothly. When we found issues they were adressed in a timely manner and the level of encryption was also very important for us. It was a very helpful tool to help us abide by the law 25.
    What do you dislike about the product?
    Some limitations regarding the segregation of reports consultation in the online site was reported. There is also the fact that the Recon engine is not running as a service.
    What problems is the product solving and how is that benefiting you?
    It helped us identify were our sensitive data was kept and made sure it was secured properly.
