How deep-learning AI and layered, real-time defence shut down attacks before they take hold
Every 11 seconds, a business is hit by a ransomware attack somewhere in the world, after which it can take a business an average of 24 days to recover from downtime (Statista). Taken as a whole, 56 percent of ransomware attacks succeeded in encrypting data in the past year, with only one in three smaller organisations managing to stop an attack before encryption took hold (Sophos: ‘State of Ransomware 2026’).
However, as reported for 2025, organisations that were using AI and automation extensively in their security managed to contain incidents significantly faster than those that didn’t (IBM: ‘Cost of a Data Breach Report 2025’).
These numbers show us that attacks are frequent, encryption succeeds more often than most businesses expect, and the cost of cleaning up afterwards is significantly more than that of stopping an attack before it starts. Prevention – done automatically, at machine speed – is consistently the cheaper option.
The New Reality of Today’s Cybersecurity Frontiers
By the time that traditional antivirus recognises a new strain of ransomware, the damage is usually already done. Files are encrypted, a ransom note is sitting on the desktop, and the business is offline.
That’s the fundamental limit of signature-based protection: it can only stop what it has already been told to look for.
Sophos Endpoint Protection, delivered through Vox Business, closes this gap. It’s endpoint protection built around deep-learning AI, designed to block both known and unknown malware, reverse malicious encryption in progress, and shut down exploits before they take hold, rather than cleaning up after them.
Traditional Antivirus versus Sophos Endpoint Protection
Conventional antivirus works from a list: a database of known malware signatures, updated by the vendor as new threats are identified, is checked against every file that lands on a device. It’s a model that depends entirely on someone else having seen the threat first.
The trouble is that ransomware operators now produce new variants faster than any vendor can catalogue them, and a single new signature is all it takes to walk straight past a signature-only defence.
Sophos Endpoint Protection takes a different approach. Its deep-learning engine is trained on hundreds of millions of malicious and legitimate files, so it assesses a file’s actual characteristics, including structure, behaviour and intent, rather than checking it against a list of names it already knows.
This means that it can identify malware it has never encountered before without waiting on a signature update, while still catching the known threats a traditional scanner would flag.
Prevention Must Work at Machine Speed to Keep Up with Attackers
Ransomware-as-a-service has turned what used to be a specialist crime into the modern-day cybersecurity version of a ‘hired gun’. Against this kind of volume and automation, a defence that only reacts once a threat is already recognised is playing a losing game.
It’s not only large enterprises with dedicated security teams that are targets: South African businesses of every size are under threat. This is exactly why prevention needs to be automatic, continuous and built in at the endpoint itself.
How Sophos Endpoint Protection Works: AI-Led, Layered Defence in Real Time
Sophos Endpoint Protection doesn’t rely on any single technique. Instead, it stacks several layers of protection so that if one is bypassed, another is already watching:
- Deep-learning malware detection: A neural network model evaluates every file in milliseconds, catching novel and zero-day threats that have no known signature.
- CryptoGuard anti-ransomware: CryptoGuard watches for the behaviour of malicious encryption in progress. When it spots malicious encryption, it automatically halts the process and rolls affected files back to their pre-attack state.
- Exploit prevention: Blocks the small set of techniques attackers use to weaponise software vulnerabilities, which stops entire categories of attack regardless of which specific exploit is used.
- Signature and malicious-traffic detection: Still catches known threats and blocks command-and-control communication, so the layers work together rather than replacing one another.
- Sophos Central management: Every layer is visible and controllable from a single cloud console.
Because these layers run continuously and in real time, rather than as a scheduled scan, Sophos Endpoint Protection is positioned to intercept an attack at the point of execution, rather than reporting on it afterwards. Paired with Sophos Firewall through Synchronised Security, a threat detected at the network edge can automatically trigger an isolation response at the endpoint, so the tools act as one system instead of five separate consoles.
With Sophos Endpoint Protection, the underlying business benefits are the same: fewer incidents reach the point of doing damage, and IT teams spend less time cleaning up after the ones that do get through. In practice, this translates into fewer disrupted trading days, fewer forced-choice conversations about paying a ransom, and IT employees who spend their time on projects rather than incident response.

Frequently asked questions
What is Sophos Endpoint Protection?
Sophos Endpoint Protection is security software for business devices, offered through Vox Business. It uses deep-learning AI to block known and unknown malware, stop exploits and reverse malicious encryption before an attack can take hold.
How is Sophos Endpoint Protection different from traditional antivirus?
Traditional antivirus checks files against a list of known malware signatures, so it can only stop threats that have already been identified. Sophos Endpoint Protection looks at a file’s structure, behaviour and intent instead. This lets it detect new and zero-day threats without waiting for a signature update, while still catching the known threats a traditional scanner would flag.
Can Sophos Endpoint Protection stop ransomware that has already started encrypting files?
Yes. Its CryptoGuard anti-ransomware feature watches for malicious encryption as it happens. When it spots it, CryptoGuard automatically stops the process and restores the affected files to their pre-attack state.
Does Sophos Endpoint Protection work with Sophos Firewall?
Yes. Through Synchronised Security, a threat detected by Sophos Firewall at the network edge can automatically isolate the affected endpoint. The two tools then act as one system, managed from a single Sophos Central cloud console. Sophos Endpoint Protection can also run on its own.
How is Sophos Endpoint Protection licensed and supported in South Africa?
Licensing is per user, billed monthly, with no hidden costs. It scales from a handful of devices to enterprise deployments. Vox is an accredited Sophos Platinum Partner with more than 200 Sophos certifications, and it provides deployment and support from within South Africa.
