There are 750,000 companies around the world that use Zoom to handle their videoconferencing needs. And now, some of them may be reconsidering their choice.

On Monday, security researcher Jonathan Leitschuh revealed in a blog post that the Mac version of the popular Zoom videoconferencing service has a severe vulnerability that could allow hackers to turn on your webcam so they can spy on you and even activate programs running on your computer that have been turned off.

Hackers can exploit the bug by sending you a link to a Zoom video meeting. From there, they can turn on your webcam and run amok. According to the security researcher, they could also technically use denial of service attacks, though Zoom has already patched that issue.

Still, as of this writing, the bug remains. And companies not wanting to expose themselves to threats or simply looking for ways to keep their businesses safe might be looking for alternatives.

The problem, of course, is that finding a suitable videoconferencing alternative to one you've been using for quite some time isn't all that simple. So, to help you with that, I've compiled the following list of three outstanding videoconferencing alternatives you can implement in your company right now:

1. Skype for Business

Skype for Business has long been one of the most popular solutions for videoconferencing. For companies, it's a nicely convenient option.

That's because Skype for Business is baked into the Office 365 services millions of companies around the globe use for their own e-mail, productivity, and word processing applications. If you have Office 365, you can simply go to Skype for Business, start a call, and you're good to go. And since it's inside Office 365, you won't need to pay an additional fee.

Most importantly, Skype for Business works well, has a nice interface, and can be deployed companywide in no time.

2. GoToMeeting

GoToMeeting made a name for itself over the last few years by delivering a compelling solution for companies that desired something a bit more appealing than standard, high-end options.

GoToMeeting works with millions of businesses currently, which allows them to hold videoconference calls with ease. You can use the app both on desktop and mobile and up to 25 people can collaborate on a high-definition feed at the same time. It'll even create a personal meeting room for you with a custom URL, so you can easily send people to your workspace.

GoToMeeting's pricing varies depending on the number of participants in your company. Prices start at $14 per month per person for up to 10 people.

3. RingCentral Office

RingCentral has become synonymous in recent years with affordable business phone systems. And RingCentral Office aims at providing exactly that--with some videoconferencing tossed in.

RingCentral Office is actually part of a broader suite of services that includes a cloud phone system, team messaging, and online fax. But you can get videoconferencing with it in HD, so you can see clearly all of your participants. The service also lets you share screens for faster collaboration and gives you the option of recording your conferences, so you don't miss important parts of the meeting.

RingCentral Office pricing varies greatly based on the number of users you want and the number of features you want. But pricing starts at $25 per person per month.

So there you have it--a look at three alternatives to Zoom that, in some cases, might deliver the same or even better performance than what you're getting now.

Of course, if you feel like you can't leave Zoom, there's a good chance that the problems will be fixed soon. And if you turn off the feature that automatically turns on the webcam when you start a meeting, you won't suffer from the problem.

But if you're unsure you can trust the company, go with one of the options above. You'll be happy you did.
