Pros:

It was easy to install the software with icinga/nagios and took only 2 hours. Flexibility of service configuration and ease of use API for custom scripts.

Cons:

Sometimes it signales to fast if we forgot to disable the monitoring for maintenance ;-)

Reasons for choosing SIGNL4

The alerting combined with on call / shift planning was the reason why we chose signl4. Others were not able to deliver this combination and we would use 2 solutions instead of one with signl4

Reasons for switching to SIGNL4

Flexibility and advanced possibilities

The App we've been searching for!

Using for emergency calls in a church. Team members love it. I love it.

Ratings Breakdown

Ease of use

Functionality

Pros:

I have been looking for an app like this for over 2 years! Finally, an emergency alert app that gives persistent notifications, and can work with iOS to even alert you when you have Do Not Disturb enabled. Since this app allows a variety of choices for the persistent alert, including a phone call from a consistent phone number, I can set the SIGNL4 phone number as a favorite in my contacts, and then my alert comes through even if I set the phone to DND (and allow favorites in the DND settings). This allows me to sleep without interruption unless there is a true emergency! This app does so much more also, scheduling team members, making sure someone is always on duty, and even making provision for unanswered alerts to be escalated to a manager after a set time frame. We use it at our Church for an emergency. What I really love is that a parishioner calls in to our church phone system and leaves a voicemail in our emergency voicemail box, then my phone emails the voicemail to SIGNL4 app and after the alert, there is the voicemail accessible by a PLAY button within the app! Thank you SIGNL4, you have thought of everything!

Cons:

Have not found anything yet that we do not like... Seems like they've thought of everything.

Reasons for choosing SIGNL4

Can receive persistent alerts even while DND is on using iOS.

We love your review! Thank you.

Absolutely reliable!

We wanted to replace the alarm with our old city call devices. This was no longer up-to-date and the reliability was not always given. With Signl4 we no longer have to hand over hotline cell phones and city call devices. The active hotliner is automatically put into service. The planning of the hotliner has become much easier. Thanks to the hotline overview, it is also more manageable.

Great product, with even better people behind it

We have worked with the people behind SIGNL4 for years, using Derdack Enterprise Alert before. We always have a good dialogue with them, and they really listen to our needs. They respond quickly if we see some issues, and fix them right away.

Pros:

It's a cloud service, with no need for servers and software installed. Perfect for our needs. The support is excellent, and when we first engaged with SIGNL4 they quickly developed the features we needed.

Cons:

Creating schedules in the app is probably the only thing we miss.

Reasons for choosing SIGNL4

Get alerts when issues arise, not when people gets frustrated and call you.

Very easy to get startet: create account, install app on phone and then just feed email adress to anything that should be able to send an alert. On a side note, app has a WAF score of -1, forgot to warn her before the first alarm came in the middle of the night...

Functionality

Pros:

It keeps alerting until someone on your team acknowledges. Push, phonecall or text, your choise. It integrates well with other systems. Just send an email or do a http POST to raise an alert. There is even support for attachments in the alert, so if you need to send a picturein the alert, its possible. Their support is super helpfull.

Cons:

I am missing a feature, heartbeat. It would be awesome to have: miss 3 heartbeats from a device and raise an alert. Should mention that they added it as a feature request, so maybe at some point.

Vendor Response

Thanks a lot, Jens. Sorry about the WAF score, we should put a sticker on the app to keep all wives happy ;)

Liked everything - and all features that were missing - the great team from SIGNL4 have implemented it after we reached out to them.
