Data loss prevention watches where sensitive files go and stops the copies that should not leave.
This guide ranks the products on which of the three channels they actually cover, what classification and tuning cost in the first ninety days, whether blocking survives contact with a works council, and what removing the agent takes.
Vendors can pay for visibility on this page. It never changes what an entry
says about a product, including the criticism, and we earn nothing when you click through to a
vendor. How that works.
In short
What data loss prevention software does
Data loss prevention inspects files, messages and uploads for sensitive content, then logs, warns or blocks when that content moves to an unapproved destination.
In this order: setup effort, what it really costs, how your data comes back out, whether
you can leave, and who each data loss prevention tool is built for. Why those five, and why there is no
score out of ten, is on the how we work page.
Very large enterprises needing endpoint, network and storage in one
Any organisation below several thousand employees
Country is where the vendor is headquartered or contracts from, which is a
different question from where your data is hosted. Where the two tell different stories, the
entry says so.
Endpoint data protection sized for companies without a security team
Ranked #1 of 12 in Best Data Loss Prevention Software in 2026.
Published pricingEurope
Safetica is the only product here a mid-sized company can buy, deploy and operate without a consultant, and the published price makes the business case arguable in one meeting. It covers the endpoint channels and common cloud applications well enough for the risks most firms actually face.
The classification engine is simpler than the enterprise engines, and the behaviour analytics need a careful internal announcement or the works council conversation starts badly.

Where it costs you
No network-level inspection of traffic you do not control
Device control and content filtering with real macOS and Linux agents
Ranked #2 of 12 in Best Data Loss Prevention Software in 2026.
Self-hostablePricing on requestEurope
Endpoint Protector treats macOS and Linux as first-class, which is unusual enough to shorten the list on its own for engineering and design firms.
Device control is the strongest module: USB, Bluetooth, printers and mounted volumes governed at a level of detail the suites rarely match, with an on-premise deployment available. Buy it knowing the quote depends on which of the four modules you take, and that content inspection is good rather than forensic.
What stands out
macOS and Linux
Device control
On-premise option
Where it costs you
Priced by module, so quotes vary widely between buyers
Content inspection is less subtle on complex document formats
Right for
Mixed estates with Macs and Linux machines that matter
Wrong for
Organisations needing inline inspection of all network traffic
Device control and encryption from a Munich vendor
Ranked #3 of 12 in Best Data Loss Prevention Software in 2026.
Self-hostablePricing on requestEurope
DriveLock is at its best on the oldest channel in this market: what gets copied to a USB stick and whether that stick is encrypted.
Port control is granular, USB encryption comes with device control while disk and file encryption are separate products, and the vendor is in Munich with a German and Austrian sovereign cloud or on-premise deployment, which settles procurement questions early. The content inspection engine is modest, the interface is dated, and anything that is not Windows gets noticeably less attention.
What stands out

Where it costs you
Content inspection is basic next to the dedicated engines

Scans the SaaS applications first, and now the laptops as well
Ranked #4 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestNorth America
Nightfall AI started on the cloud third of the problem and still does it best. The API connectors deploy in minutes and find keys, tokens and personal data sitting in Slack channels, Drive folders and ticketing systems where nobody remembers putting them.
Detection of secrets is its strength. macOS and Windows agents installed through MDM now cover uploads, USB, clipboard and git pushes, so check whether that endpoint coverage is deep enough before treating it as a replacement for an endpoint product.
What stands out

German endpoint data protection with the privacy story written in
Ranked #5 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestEurope
Matrix42 EgoSecure Data Protection is built around a German assumption: that an administrator should not be able to read employee activity alone. Four-eyes release of audit data is the feature that closes works council objections, and it is not cosmetic.
The product is strongest on endpoint channels and device control on Windows, weaker in the cloud, and priced by module, so insist on a quote for the exact combination you will actually switch on.

Cloud-first companies whose data never touches a Windows laptop
Follows where a file came from as well as what it contains
Ranked #6 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestNorth America
Cyberhaven changes the usual model: besides asking what a file contains, it remembers where the content came from, so a screenshot of the salary sheet or a renamed CSV export is still recognised.
That shrinks the classification project that stalls most deployments and cuts false positives sharply. The limits are commercial and architectural: a young vendor, enterprise quoting, and enforcement that leans on the endpoint agent and browser extension, with cloud connectors for data at rest.

Already paid for if your licence says E5, with no new agent
Ranked #7 of 12 in Best Data Loss Prevention Software in 2026.
Published pricingNorth America
For an E5 customer this is already bought, needs no agent, and enforces in the places most leaks actually happen: email, SharePoint and Teams. That combination is hard to argue against on cost.
Outside Microsoft it leans on Edge for Business, Defender for Cloud Apps or a partner proxy, and endpoint coverage, built into Windows and onboarded on the three latest macOS versions, is a step behind the specialists. Expect a slow authoring experience and policy changes that take about an hour to take effect, which makes tuning a patient exercise.
What stands out

Inline inspection of everything leaving the browser
Ranked #8 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestNorth America
Netskope inspects traffic inline, which is how it sees uploads to the eleven file-sharing sites nobody knew staff were using. That visibility is unavailable to any endpoint agent.
It is also a platform commitment: a client on every device, traffic steering to maintain, and a quote that only makes sense when web filtering and private access come with it. As a standalone data loss purchase it is the most expensive way to get there.
What stands out
Inline proxy
Cloud app coverage
Quote-only
Where it costs you

Data rules attached to the proxy your traffic already crosses
Ranked #9 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestNorth America
Zscaler Data Protection is a licence decision for companies whose traffic already crosses the proxy, and a large project for everyone else. Inspecting decrypted traffic at the proxy catches uploads that no endpoint agent sees, including from unmanaged browsers on managed networks.
The two things to settle before signing are the TLS inspection policy, which needs legal and works council sign-off in Europe, and which bundle edition actually includes the data features you were shown.

Deep endpoint visibility, usually run as a managed service
Ranked #10 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestNorth America
Fortra Digital Guardian records file activity in enough detail to answer how a document left, not merely that it did, which is what an investigation actually needs.
Most customers take it as a managed service because the alerts need analysts, and that is the honest reading of the price. If you intend to run it yourself, ask hard questions about staffing, and test the agent's effect on developer machines before committing.

The largest policy library, and the tuning bill behind it
Ranked #11 of 12 in Best Data Loss Prevention Software in 2026.
Pricing on requestNorth America
Forcepoint DLP has the deepest policy library in this market and exact-data-match fingerprinting that identifies your actual records rather than anything shaped like them, which is why auditors in finance and healthcare recognise it.
Getting there costs a partner engagement and months of tuning. Organisations that buy it without assigning an owner end up running three policies in monitor mode, which any cheaper product on this page would have done for them.
What stands out
Regulatory templates

Symantec Data Loss Prevention still covers more of the problem than anything else here: endpoint agents, network inspection and discovery scans across file shares and databases, driven by a detection engine with twenty years of refinement behind it.
The difficulty is buying it. Under Broadcom the commercial focus sits on the largest accounts, and smaller customers describe renewals and support that reflect that. Shortlist it at enterprise scale, and skip it below.

United StatesQuoted per organisation, enterprise agreements
Data loss prevention inspects files, messages and uploads for sensitive content, then logs, warns or blocks when that content moves to an unapproved destination. The differences that matter are rarely in the feature list, so this is
the order we would work through them.
01
Decide whether you need a published price
2 of the 12 tools here publish what they cost; the other 10 quote per organisation. The ones you can compare without a sales call: Safetica, Microsoft Purview Data Loss Prevention.
02
Decide how much the jurisdiction matters
These 12 vendors are established in 4 countries across 2 regions (North America 8, Europe 4). That decides whose disclosure law applies to what the vendor holds, wherever the servers are.
Endpoint, network and cloud are three products, not one
This is where most data loss prevention budgets are misspent. An endpoint agent sees USB drives, printers, local files and what an application does on the device. Network inspection sees uploads crossing a proxy, including from browsers and devices the agent never reached. Cloud coverage means scanning what is already sitting in Google Drive, Slack or GitHub through their APIs.
Most products now claim all three, so ask which one they were built for: Safetica, DriveLock and Matrix42 started on the endpoint, Netskope and Zscaler at the network proxy, Nightfall AI in the cloud APIs, and the later channels are usually thinner. Map your top five leak scenarios to a channel before reading a single feature list, or you will buy a third of the product you needed.
Write your five most likely leak scenarios and label each one endpoint, network or cloud.
Ask every vendor which of the three they cover natively, and which needs a second product.
Check whether unmanaged devices and personal browsers are in scope, because agents never reach them.
Classification is the project, and nobody budgets for it
A rule that matches anything resembling a bank account number will fire on invoices all day. The accuracy ladder runs from regular expressions, through dictionaries and document fingerprinting, to exact data matching against your own records, and each rung costs more setup. Forcepoint DLP and Symantec Data Loss Prevention sit at the accurate end and expect that work to be done.
Cyberhaven shortens the ladder by tracking where content came from as well as what it looks like, which is the most interesting idea in the category. Whatever you buy, start with two or three data types that a court or a regulator would name, not with everything sensitive, and expect a fortnight of tuning per type before blocking is defensible.
Pick two data types to start, and write down what a true positive looks like for each.
Feed the tool real historical files during the trial and count how many alerts were wrong.
Ask whether exact data matching is included in the quoted price or sold as an upgrade.
Blocking, coaching, and the works council
In much of Europe the decision is not technical. Monitoring what employees do with files is processing personal data, and in Germany, the Netherlands and France the works council usually has to agree before the agent is switched on. That agreement is easier to get with three commitments: log the minimum, warn the user rather than silently block, and keep audit access under two pairs of eyes.
Matrix42 EgoSecure Data Protection and Safetica are built for that conversation, and Fortra Digital Guardian's depth of endpoint recording is exactly what makes it a harder sell. User coaching also works better operationally, because a warning that explains the rule produces a ticket, while a silent block produces a workaround.
Take the data protection impact assessment to the works council before the pilot, not after.
Configure a user warning with a business reason box before you configure any hard block.
Restrict who can read the activity logs, and log the reading of them too.
The bill after the pilot, and getting the agent back off
Quote-only pricing dominates here for a reason: the number depends on modules, endpoints and whether analysts come with it. Endpoint Protector by Netwrix and DriveLock price by module, so a quote for device control alone is not comparable with a suite. Add the operating cost nobody quotes: someone triages alerts every morning, and without that person the product runs in monitor mode forever.
Exit is the other neglected cost. Policies do not port between vendors, fingerprint databases certainly do not, and removing a deeply installed agent from a few thousand machines is a project of its own. Keep policy definitions documented outside the console and export incidents continuously.
Get the quote for year three including modules, renewal uplift and any managed service.
Name the person who triages alerts daily before signing, not after deployment.
Test agent removal on a sample of machines during the pilot, including locked-down ones.
What goes wrong most often when buying data loss prevention software
Buying an endpoint agent when the actual risk was staff uploading files to personal cloud accounts from unmanaged browsers.
Turning on every prebuilt policy at once. The alert queue becomes noise within a week and nobody looks at it again.
Starting the pilot before the works council and the data protection officer have seen what will be recorded.
Assuming the classification work transfers to the next vendor. Fingerprints and policies are the one asset you cannot export.

Frequently asked questions
7 answers
What is the best data loss prevention in 2026?
Safetica leads our ranking of 12. The rare product in this market with a price on the website and a deployment measured in days. Covers endpoint channels and the common cloud applications, with user behaviour reporting attached.
Beyond SSL inspection of web traffic on its own agent, network-level inspection is not its game, the classification engine is simpler than the enterprise products, and reporting that flatters a manager can read as employee monitoring if nobody manages the rollout carefully.
Which data loss prevention tools publish their pricing?
2 of the 12, with the pricing model each one publishes:
Safetica: Per user per year, published.
Microsoft Purview Data Loss Prevention: Purview Suite at $12 per user per month on top of Microsoft 365 E3, published; included in Microsoft 365 E5.
The other 10 quote per organisation.
Is there a free data loss prevention tool?
No. None of the 12 offer a usable free tier.
Where are these data loss prevention vendors established?
In 4 countries across 2 regions: North America 8, Europe 4.
Safetica: Czechia.
Endpoint Protector by Netwrix: Romania.
