GoTo Meeting has very good encryption on all the data but it lacks file transfer features.

Zoom has a lot more integrations with third-party apps and comes with a free version.

GoToMeeting and Zoom are very good web conferencing tools, and both can be used for personal or business purposes. But if you’re choosing between GoTo Meeting vs Zoom, in this article, we will try to present all the key elements to help you make the right decision.

What should I look for in web conferencing software?

The best quality of a web conferencing tool is reliability. A tool that you can trust is better than anything, but there are a few other key elements you should consider:

Now that we understand some key aspects, let’s see how GoToMeeting and Zoom can help you.

GoTo Meeting vs Zoom: which one is better in 2023? GoTo Meeting

GoTo Meeting is a web conferencing tool with a very simple interface but plenty of features to go around whether you decide to use it for personal or corporate needs.

It is focused on security, so the screen-sharing data, keyboard/mouse control data, and text chat information are TSL-encrypted in transit and AES 256-bit encrypted at rest.

Also, they use an SRTP with AES-128-HMAC-SHA1-based protocol to encrypt video and audio data and keep them secure at all times.

You may launch meetings directly from Slack, Outlook, Chrome, or Salesforce, and there are a lot of integrations to go around.

⇒ Get GoTo Meeting


Zoom is definitely a much more popular web conferencing software than GoTo Meeting. The key elements that made it so loved by the users are that it has a free version and the UI are very easy to use.

However, the best part of Zoom is the integration with over 2000 third-party services and apps that can transform it into a proficient communication tool for everyone.

It comes with recording, presentation modes, file transfer, and even live transcripts that can be used for later meeting reports.

Even with a free version, you can host and participate in video meetings of up to 100 people.

⇒ Get Zoom

1. Audio & video quality GoTo Meeting – Crisp sound and HD cameras

GoTo says that their conferencing tool, Meeting, has crisp sound and excellent video quality.

GoTo Meeting provides up to 25 webcam streams, and the resolution depends on how many attendees are in the session. A single webcam stream can be up to 1280x720px (720p).

However, if you go 1 on 1, you can use the Full HD resolution of your webcam without any issues. But in the end, it all comes down to your internet connection and the webcam quality.

Zoom – Not the best at all times

We have some guides on our website on how to fix the microphone not working on Zoom, freezes, and other problems.

But the main cause of those problems was a poor internet connection, not the app itself.

Expert tip:

2. File sharing capability GoTo Meeting – No file sharing

GoTo Meeting doesn’t have a file-sharing capability, which can be frustrating for a meeting. Of course, that can save a lot of bandwidth, but it’s still pretty inconvenient to rely on other tools.

Zoom – File sharing within chat

There is even a captioning tool available to instantly share something on your screen.

3. Seamless integration GoTo Meeting – Only essentials

GoTo Meeting has only 28 third-party app integrations, among which we can highlight the Office 365 apps, Salesforce, Slack, and Calendly as the most important.

That is because GoTo Meeting is pretty new in this market, and the publishers want to keep things as simple as possible.

Zoom – The integration master

There are 2,363 apps in the Zoom app marketplace, of which 2,142 are just for Zoom Meetings. We declare Zoom the clear winner in this department.

There is little chance of not finding the integration you need. There are apps from absolutely all categories including financial, productivity, CRM, communication, office, and many others.

4. Pricing

While Zoom has a free version, GoTo Meeting only has a 14-days demo for the product.

GoTo Meeting has a professional plan starting from $12/organizer/month which can set the limit to 150 participants per meeting.

Zoom has a $14.99 Pro account that offers 5 GB of cloud storage, 30-hour meetings with up to 100 attendees, and some premium apps for free for 1 year.

Both have additional plans that you can explore further on their respective websites.

GoTo Meeting vs Zoom conclusion

Both apps are great for web conferencing, but GoTo Meeting lacks file transfer capabilities.

Also, Zoom has a free version that can be used for personal needs, while GoTo Meeting only comes with a limited demo.

Overall, Zoom comes up as a winner, but it all comes down to testing them yourself and finding the best match for your needs.

Ultimate Troubleshooting Guide For Windows 7/8/10 Homegroup Connection Issues

Previously, I wrote an article on how to setup and configure a Windows HomeGroup. It’s a fairly straight-forward process and most people will not have issues getting it to work. However, as with any complicated feature of Windows, things can go wrong!

One of the main problems is that people simply cannot join a Windows computer to a homegroup! Homegroups are different than workgroups because they are supposed to make networking between Windows 7/8/10 computers super simple. Workgroups are what you had to use to share data between Vista and XP computers, though you can join an XP computer to a homegroup also.

Table of Contents

Run the Troubleshooter

It will automatically check all the settings required for the homegroup to function properly and tell you whether there is a problem or not. Usually, it can also try to fix any potential issues.

IPv6 Must Be Enabled

Note that sometimes the registry setting does not get updated even though you enable IPv6 via the GUI interface. So you can check the setting in the registry by going to the following key:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpip6Parameters Connected to Same Network

Though this might sound obvious, you need to make sure the computer is connected to the same network the HomeGroup is on. Only computers on the same subnet will be able to connect to the HomeGroup, so if you have a wireless router, it would only be the computers connected to that router.

You can check if your computers are on the same network by going to the command prompt and typing in IPCONFIG. The first 3 parts of the IP Address should be the same, i.e. 192.168.0.x or 10.0.1.x.

HomeGroup Password

Make sure that the HomeGroup password has not changed. You can check the HomeGroup password on another computer and then use that one to join the HomeGroup.

If you need to, change the HomeGroup password on the computer you are trying to connect to the HomeGroup.


Make sure any third-party firewalls are disabled like Comodo, etc. Sometimes anti-virus programs also come bundled with firewall software like Norton, McAfee Security and Kaspersky. These program can block the connections and prevent you from connecting to a HomeGroup.

Under the Private profile only, make sure to select Turn on file and printer sharing. This should automatically add the rule to the Windows firewall also for the private profile. Also, you want to enable on more setting here, which I mention below.

Turn on Network Discovery

Make sure that the Turn on network discovery radio button is selected. It should be on by default, but if someone changed your settings, this could also cause the problem.

Synchronize Clocks

Go to each computer and make sure that all the clocks are showing the correct time. If the clocks are not synchronized, the HomeGroup feature will not work. If your computer is connected to the Internet, it should automatically pick up the correct time.

The only occasion where it would not is if you are in a domain, then the clocks should be synchronized to the domain controller. You may have to check the time server settings if that is not the case.

Windows 7/8/10 Services

In order for the HomeGroup networking feature to be working, there are certain Windows services that need to be enabled and running. If you used a program to disable services or manually disabled them, it may be causing the problem.

The services that need to be turned on are listed below:

DNS Client

Function Discovery Provider Host

Function Discovery Resource Publication

Peer Networking Grouping

HomeGroup Provider

HomeGroup Listener

SSDP Discovery

UPnP Device Host

Set Network Location to Home

Another reason why you can’t access your HomeGroup is because it only works for home networks where you trust all the computers. If, for some reason, you chose Work, Public, or Domain, then HomeGroups will not work.

Router Supports IPv6

This is pretty much not an issue anymore, but just for the sake of covering all bases, you need to make sure that your router can support IPv6 protocol. If not, Windows 7/8/10 cannot communicate with the other computers using HomeGroup. Any relatively new router will support it, so unless you have a really old router, you should be ok.

Zoom Will (Finally) Roll Out End

Everyone’s favorite video meeting program, Zoom, announced today that it plans to roll out end-to-end encryption across all plans and users, including those on the free tier. It will be available by July.

The news is a very welcome 180 from Zoom’s previous claims  (around two weeks ago) that it would not add the security precautions to its free users. What happened in between? A backlash from civil rights groups and concerned users.

Zoom’s Record on Security

If you first heard of the video conferencing app Zoom in March due to the rapidly instituted pandemic lockdowns, you’re not alone. Zoom’s daily active users sky-rocketed from 10 million to well over 200 million within just three months.

Ballooning twenty times larger is a tough scaling problem for anyone, and the fact that security concerns resulted from fielding untold millions of private conversations shouldn’t come as a surprise.

Zoom debuted a 90-day plan to bolster security in late April, including an updated Zoom 5.0 software version that came with better encryption, more privacy controls, and a waiting room feature to ensure party-crashers couldn’t just show up without approval.

But all those changes came after a host of articles highlighting Zoom’s security issues — like this lengthy but well-sourced callout article on Medium from earlier in April. Now, a similar security problem and the subsequent backlash has spurred another upgrade today.

Zoom Encrypting Free Calls

Zoom CEO Eric Yuan kicked off the new conversation on June 2, with his statement that Zoom wouldn’t bother encrypting the data from free users’ conferences, despite rolling out end-to-end encryption to paying users as a part of its 90-day security plan.

His reasoning: Zoom needed to be able to cooperate with law enforcement.

“We want to give [end-to-end encryption] to at least the enterprise customer or business customer. Free users, for sure, we don’t want to give that,” Yuan told analysts in a conference call. “Because we also want to work together, say, with FBI, with local law enforcement in case some people use Zoom for the (sic) bad purpose, right?”

One potential response here is that bad actors might still have the money to pay for a plan. But a better one is to argue that everyone deserves basic security even if they can’t pay a premium for it.

That seems to be the tack taken by many of the activists and encryption experts that Zoom consulted with as well, given Zoom’s dramatic about-face on the topic.

Is Zoom Safe Now?

Zoom will definitely be a more attractive free video conferencing choice once the end-to-end encryption is in place for all users.

Still, if the back-and-forth on Zoom’s security has left you a little leery, we can’t blame you. Even with the July update, meetings’ hosts will have to manually turn on the end-to-end encryption option, so it is not a guarantee that you’ll be protected when you’re not the host yourself.

If you’re hunting for alternative options, look no further than our list of the top ten communication apps available to you.

And if you’re willing to pay for the benefit of some iron-clad security, we also have a roundup of the best VoIP services for businesses.

The bottom line here: Zoom made the right call in expanding its encryption protocols to all.

The video app shouldn’t be blamed for its growing pains. But the fact that the company needed to be repeatedly pushed to action by public backlashes is not really a good look.
