I have written before about being cautious concerning any VPN providers who claim they are not keeping logs.
Just this morning, I was sent an email concerning several VPN providers who had their data dumped onto the Internet, proving they had been keeping logs while claiming they do not keep logs.
This is more proof that you should never trust a “no logging” VPN service to not keep logs.
Now am I saying that using a paid VPN is useless? No, but you need to be careful which VPN service you are using. In my experience, very few are legitimate, and even the legitimate ones are probably logging enough data to eventually identify you.
VPN services are in it for the money and most will say anything (e.g., “no logs”) to make a quick buck. Not to mention they could be selling your user data on the side – a double-whammy.

A couple weeks ago, someone online posted a comment saying you can stay “safe and secure” online due to using the web browser’s incognito mode.
Is this true. Does incognito mode really prevent someone from ever tracking you online?
Short answer: no
People believe the myth that the incognito mode – on your web browser – will keep you safe and private. However this is not the case.
Incognito mode only does the following:
- prevents web history from being logged locally
- prevents download history from being logged locally
- prevents cookies & cache data from being stored locally
In other words, incognito mode will prevent someone from spying on you, just by opening the web browser and viewing the web history and downloads.
Now what does incognito mode not protect against?
- Malware on the system — Any malware on the system will be totally unaffected by your use of incognito mode.
- IT department — Your IT department will still be able to track your Internet usage on their network. This is especially true if you use their local DNS resolvers. They will know what websites you visit, regardless of your use of incognito mode.
- Internet Service Provider — Unless you make use of a VPN service, your ISP will definitely know where you go online, regardless of your use of incognito mode.
- Government surveillance — Of course, incognito mode will be of no use to you here. Also, even using a VPN will not help much if you are being targeted by a government.
The link below helps prove that any browser being in “private” or “incognito” mode (whatever you want to call it) does nothing to prevent 3rd parties from spying on you.

Many people use VPNs for their Internet connections, in the attempt to prevent their Internet Service Providers (and others) from seeing what they do while on the Internet.
These VPN services tunnel all of your web traffic (everything you do with your Internet connection, not just data from web browsing) through their servers.
( Of course, VPNs are also used for connecting two remote locations together over the Internet, but that is outside the scope of this post. )
While a VPN service can potentially help to protect your privacy, there are many myths people believe about VPNs.
1 : VPNs will prevent hackers from hacking into my computer
First off, if your computer has an open attack vector facing the Internet, you will eventually get hacked sooner or later.
Secondly, VPNs do not stop malware from infecting your computer (thus allowing a hacker into your computer), nor does it prevent a hacker from learning your real IP address and trying to attack your computer directly.
2 : No malware can get onto my computer while using a VPN
As mentioned above, VPNs do not stop malware from infecting your computer. The VPN service will download that malware-infested file just as happily as your ISP would have.
Your best defense against malware, is a good anti-virus/anti-malware application (e.g., Windows Defender or Malwarebytes), and using common sense when downloading something off the Internet (e.g., does the website you are downloading the file from look sketchy?).
I am aware that some VPN providers provide a feature that blocks malware and ads for you automatically. This is just the VPN provider blacklisting known malware and ad-tracker domains. The VPN itself is not protecting you. It is the blacklists on their DNS servers that are protecting you.
You can provide yourself the same kind of protection by running a Pi-Hole device on your network.
Of course, it is more user-friendly to have a VPN service automatically do this for you, instead of doing it yourself.
3 : VPNs will get past all geo-restricted websites
While VPNs can successfully access geo-restricted web content, some content providers (e.g., Netflix and Steam) disallow VPNs of any kind (according to their Terms of Service). However telling someone that VPNs will always work with geo-restricted websites is just plain false information.
As an IT administrator, I know that not logging anything is pretty much impossible, since logs are necessary to help fix critical problems. It is up to you to decide who to believe when it comes to “no logs”. After all, you are using their network, not your own. Ultimately you are just taking their word for it.
In addition, the VPN’s upstream ISP most certainly will log all traffic. So by using traffic analysis attacks, your real IP may be uncovered anyway.
5 : I can be an outlaw online, since I use a VPN
No VPN will completely protect you if you are doing something to attract the attention of a large, well-connected organization (e.g., a government agency). So if you are thinking about doing something illegal online (via a VPN), you better just forget it. You will get caught sooner or later.
6 : I am completely anonymous to my VPN provider
This one can be semi-true. There are VPN providers that only require an email and can be paid in cryptocurrency (e.g., Bitcoin). However, unless proper steps are taken, your Bitcoin payments can still be tracked.
Also, your VPN provider will know your real IP address, which could (please notice I said “could” not “will”) be leaked to certain people which may then expose your identity.
7 : Anything I send over a VPN is completely secured from prying eyes
A VPN service does not provide point-to-point security. What I mean is that if you access my blog (via HTTPS) through a VPN, your initial connection is encrypted both at the browser and the VPN connection you have established.
However that extra security stops at the VPN itself. Whatever you transmitted to my server gets sent out as if you never used a VPN to begin with after it leaves the VPN’s server.
If you are using a HTTPS enabled website, neither the VPN provider nor anyone else can look at the contents you are transmitting.
On the other hand, if you use a website that has no HTTPS (HTTP-only), then both the VPN service and anyone else (after the data leaves the VPN) can not only snoop your traffic, but they can also modify it. Not good.
8 : All VPN services have full control over their servers
While it is true that most (if not all) VPN services own their own servers (dedicated or VPS), this does not necessarily mean they have full, complete control over their servers.
Why? Simple. Unless they acquire their own data-center, the VPN company has no real idea of what is happening to their servers. This may not bother you, but it is a potential vector for a security breach of customer information.
9 : With a VPN, you will be anonymous everywhere you go online
There are three problems with this idea.
First, there is no way to be 100% anonymous online. That is a myth.
Secondly, assuming your VPN is not a bad actor itself, the minute you login into a personal account (e.g., Facebook, Twitter, Google, Bing, etc.), you will have just identified yourself to the remote computer.
Third, a VPN service cannot stop web tracking methods like tracking cookies and web browser fingerprinting.
Now you may be asking, “How does this allow someone to track my online visits?” Good question. A web browser fingerprint is the identification of someone’s web browser in an attempt to track you regardless of what IP address you are coming from.
Basically your web browser is probed to determine what add-ons you have installed, what fonts are installed on your computer, what video card your computer has (via WebGL), PNG hash, what operating system you are using, your web browser’s 2D canvas, etc. All of this information is combined to form a fingerprint of your web browser.
If you have ever visited a website (without using a VPN) and later on you visit the same website (this time, using a VPN), they can still have a pretty good guess that it is you just by looking at your browser fingerprint you left the last time you visited (without the VPN).
Web browser cookies work in a similar manner. If you do not delete your cookies every time you exit a website, later on when you visit that same website again, they can read the cookie they placed in your web browser and know it is you, even if you are connecting under a different IP address via a VPN service.
web cookies used for good – online shopping cart, logging into your webmail
web cookies used for evil – tracking your visits to spy on you and sell the collected information to 3rd-parties…or worse
10 : “My Internet service gets 100/10 (download / upload) speed, so the VPN service I purchased will give me the same download/upload speed”
This one can sometimes be true, but usually isn’t. You have to understand that there are usually so many customers on any particular VPN server, that the bandwidth is strained between all the users.
If you have 100 people each using 10 Mbps of download bandwidth, there is not going to be much bandwidth left for anyone else to use, if the server does a max of 1000 Mbps.
If you have a 100/10 Internet service, you are doing good if you get 50/8 on a VPN. I am not saying that all VPN servers are slow, but in my experience, most of them are. If you have very fast Internet service, don’t expect to utilize all your bandwidth with a VPN service.
11 : “My VPN service has been audited. It has been verified to not be keeping user logs.”
I have heard of a commercial VPN service being audited to “confirm” no logs are being kept. Unfortunately this means nothing.
You are just having blind-faith in what some audit company says. Unless you have personally inspected each and every section of the VPN service’s network, you really have no clue if it really is secure or not.
It’s your business whether or not to believe an audit, but I personally consider it unwise.
I hope this post has helped dismantle some myths you may have heard online about VPN services.
So what is the best use for a VPN service?
1) hide your activity from your ISP or untrusted network (does not prevent governments from tracking you down)
2) prevent the remote computer (e.g., web-server) from knowing your real IP address
3) circumvent Geo restrictions (not always reliable and may even be violating the “Terms of Service” of the service you are accessing)
Using a VPN for anything other than those three specific reasons will result in a false sense of security for you. Also, as mentioned before, this all assumes that your VPN provider is a good guy. After all, you are sending your data through their network. Since they have become your “new” ISP, they could sell your data for a pretty penny, and you would be none the wiser.
Please Note: I did not write this post to scare you away from using a VPN provider, but I wanted to make sure people understand that a VPN service is not a “magic pill” that will cure all of your online web privacy problems (as many people seem to think).
Using a VPN for the purpose of preventing your government from spying on you or being 100% anonymous on the web is pointless.
