No. A VPN does not stop spyware that is already installed on your device. It encrypts network traffic routed through its connection, helping protect that data while it travels across an untrusted network. Spyware operates on the device itself and may monitor information or functions there. The two tools address different risks: a VPN can protect some data in transit, while security software and careful incident response address suspected malware on a device.
What does a VPN protect, and what does spyware do?
A VPN creates an encrypted network connection. The UK National Cyber Security Centre (NCSC) describes VPNs as a way to provide secure connectivity between devices in different locations and protect data in transit across an untrusted network. That protection applies only to traffic routed through the VPN; the NCSC states, “Only traffic which is routed over the VPN will be protected by it.” Its guidance is written for organisations choosing and configuring VPNs, not as a consumer product comparison.
Spyware is software on a device. The Federal Trade Commission (FTC) describes stalkerware—a form of spyware—as software or an app that may be installed on a phone or another device without the owner’s knowledge. Depending on what it can access, it may track location, read communications, access photos and videos, turn on a microphone, or monitor online activity.

Those functions explain why encryption alone is not a spyware-removal or detection tool. A VPN can protect certain data as it travels over a network connection, but it does not itself scan the device for software or remove software already running there. The distinction is between protecting a communication on its route and addressing what is happening on the device that sends or receives it.

Can a VPN stop spyware from tracking my phone?
Not if the spyware is already on the phone and can access the information or functions it is monitoring. A VPN does not take away an app’s existing access to device data, such as location or messages, and it does not establish that a phone is free of spyware.
For example, if stalkerware can access location information on a phone, changing the route that some network traffic takes does not remove that access. A VPN may encrypt traffic routed through it, but the FTC’s descriptions of stalkerware concern software installed on the device and what it can monitor there. Do not assume that using a VPN prevents another person from learning information that an app on the device can access.
There is a separate situation in which a VPN may help: protecting traffic that actually passes through it while travelling across an untrusted network. That benefit is about data in transit, not a guarantee that the phone, its apps, or its accounts are safe. Whether a particular app’s traffic is routed over a VPN depends on the device setup and routing; the NCSC cautions that not all traffic is necessarily protected.

What does a VPN not do against spyware?
A VPN is not a substitute for device-level malware protection or a response plan. It does not, by its network-encryption function, establish whether spyware is installed, find hidden software, or remove an infection.
Rank #2
- It does not scan your phone or computer. Encryption of routed traffic is different from checking files or apps on a device for malware.
- It does not necessarily cover every connection. The NCSC says only traffic routed over the VPN receives its protection. Device setup, routing, and whether the connection stays active affect the scope.
- It does not undo device access. If spyware can read messages, access photos, or monitor a device function, encrypting network traffic does not itself revoke that capability.
- It does not make an account secure by itself. If login credentials have been exposed, a VPN does not change those credentials or enable stronger account authentication.
These are limits of what a VPN does, not a claim that VPNs cause spyware infections. VPNs can be one layer of network security, but they are not a complete security control for a device or network.
Can malware get onto a network even when VPN access is used?
Yes. A CISA incident report documents a threat actor who authenticated to an organisation’s VPN appliance, connected to its network, installed SUPERNOVA malware, and collected credentials. The accounts used in that incident did not have multi-factor authentication enabled.
This is a specific incident example, not a measure of how often such events occur, and it does not show that a VPN caused the infection or failed to remove spyware from a device. It illustrates the narrower point that VPN access alone does not guarantee that a network or connected device is malware-free. Authentication and other security controls matter too.

Unusual device behaviour can be a reason to investigate, but no single symptom proves that spyware is present. The FTC suggests considering unexplained battery drain, unusually high data use, overheating, unexpected restarts, or another person knowing private location or conversation details.
Stalkerware can be designed to avoid detection and may appear under a misleading name in device settings, according to the FTC. That means a quick visual check may not settle the question either way. Treat symptoms as clues rather than a diagnosis, and seek trusted technical support if you need help assessing the device.
- Consider whether the change is new and unexplained, rather than assuming a familiar performance issue is spyware.
- Pay attention to private information another person appears to know, especially if you have not shared it with them.
- Do not treat the absence of visible symptoms as proof that no spyware is installed; the FTC notes that stalkerware may be difficult to detect.
What should I do if I suspect spyware or other malware?
The appropriate response depends partly on whether this is a general malware concern or a safety-sensitive stalkerware situation. For suspected malware, the FTC recommends using security software, updating it, and running a scan; it also advises stopping logins to sensitive accounts on the affected device and changing passwords if credentials may have been exposed.
If you suspect malware and there is no immediate personal-safety concern
- Stop using the device to sign in to sensitive accounts. This reduces the chance of exposing more account information while the device is being assessed.
- Update your security software and run a scan. The FTC recommends security software for malware protection and an updated scan when malware is suspected. A scan is a response step, not a guarantee that every possible infection will be detected.
- Protect accounts whose credentials may have been exposed. Change the relevant passwords and enable two-factor authentication, as the FTC advises. If you cannot tell which accounts are affected, contact trusted technical support for help deciding what to secure.
- Ask for help if needed. The FTC suggests contacting the device manufacturer or trusted technical support when you need assistance.
If the concern involves an abusive partner or ex-partner
Make personal safety the priority. The FTC warns that stalkerware may be difficult to detect; actions taken on a monitored device could create risk if they alert the person responsible. Consider getting help from a trusted person or specialist support using a device you believe is safe before making changes. Do not assume that removing an app, changing settings, or running a scan is risk-free in this situation.
How do VPNs and security software differ?
They address different parts of the problem, so choosing one does not make the other redundant. A VPN concerns network traffic routed through its encrypted connection; security software is the device-level category the FTC recommends for malware protection and scanning.
Rank #4
| Security layer | What it addresses | What it does not establish |
|---|---|---|
| VPN | Encryption of traffic routed through the VPN while it travels across an untrusted network, as described by the NCSC. | Whether spyware is installed on the device, whether all traffic is routed through the VPN, or whether malware has been removed. |
| Security software | Device-level malware protection and scanning recommended by the FTC. | A guarantee that every type of spyware or malware will be detected. |
| Account security steps | Password changes and two-factor authentication when credentials may have been exposed, as advised by the FTC. | Removal of spyware from a device or protection of traffic that bypasses a VPN. |
| Trusted technical support | Help assessing a suspected infection or deciding how to respond. | A substitute for personal-safety planning where stalkerware may be connected to abuse. |
There is no product-by-product performance comparison established here, and no tool can be said on this evidence to detect every spyware type. The useful distinction is functional: a VPN protects only traffic routed through it, while malware response requires device-focused steps.
What should I check before relying on a VPN?
Check whether the connection covers the traffic you care about rather than assuming the VPN protects every app and connection. The NCSC guidance notes that device setup and routing affect protection, and that a connection’s continuity matters.
- Routing: Is the relevant traffic actually sent through the VPN?
- Coverage: Could some apps or connections bypass it?
- Connection state: Does the VPN remain active when you expect the traffic to be protected?
- Threat type: Are you trying to protect data in transit, or are you concerned about software or account access on a device? A VPN addresses only the former, and only for routed traffic.
The NCSC’s VPN guidance was published on June 29, 2021 and reviewed May 13, 2025. It is useful for understanding the technical scope of VPN protection, but it is organisational guidance rather than a consumer VPN product test.

No. A VPN can encrypt traffic routed over its connection, but it does not stop spyware already installed on a device, detect it, or remove it. If you suspect spyware, treat that as a device and possibly account-security issue: use updated security software and a scan, protect potentially exposed credentials, and seek trusted support. If stalkerware may involve an abusive person, account for personal safety before taking action.
Frequently Asked Questions
Can spyware see my browsing if I use a VPN?
A VPN does not prevent software on the device from monitoring activity it can access. Whether network traffic is encrypted by the VPN depends on whether that traffic is routed through the connection.
Can I use a VPN to check whether my phone has spyware?
No. A VPN encrypts certain network traffic; it is not a device scan. The FTC recommends updated security software and a scan when malware is suspected.
Does a VPN protect me if someone has my account password?
A VPN does not change a compromised password or enable stronger authentication for an account. If credentials may have been exposed, the FTC advises changing passwords and enabling two-factor authentication.
Could a spyware app be hidden in my phone’s settings?
Yes. The FTC says stalkerware may be hidden behind a misleading name in device settings and can be designed to avoid detection. An unfamiliar or absent app name therefore does not, by itself, settle whether monitoring software is present.
