About Cilter

93% of 8 to 13 year-olds have their own smart device. 25% of 6yr olds have their own device. These numbers are growing rapidly. Risks to children online go far beyond exposure to pornography and inappropriate content. Today the risks have evolved to include bullying, harassment, coercion, blackmail, grooming and access to self-harm or suicide methods. Parents need a robust parental control that is not simply a monitoring tool.

Cilter is child-protection software that makes internet use safe for children by analysing ALL data both coming into and going out of the device, filtering it for offensive content and then alerting parents if there is an imminent threat to their child. Children are bullied, coerced, harassed and groomed through communication channels on their devices.

Cilter is built into the Operating System of the phone so it has access to all data and communications allowing it to effectively detect the signs of potentially damaging content and take action by blocking and informing parents. If your child is being bullied, those messages will be blocked. If your child searches for suicide or self-harm you will be alerted and if we detect a grooming pattern, you will be alerted and advised on next steps, if your child tries to send a naked photo that photo will not send.

Cilter Features Summary

Cilter Analyses, Filters/Blocks and Alerts parents


Cilter looks at all data entering and leaving the device for signs of inappropriate content, harm and imminent danger to your child. This is done locally on the device, so it does not rely on wi-fi connection.

Powerful Real-time Analysis

Cilter has all of the standard features but, crucially, filters and blocks offensive communications, including encrypted messages.

Filter & Block

Cilter is a two-way system. If Cilter detects content that could cause direct harm to the child, that content will be blocked. Conversely, if the child tries to send harmful content, those messages will not send.

Filters Incoming & Outgoing Data

With two-way filtering, Cilter will stop your child from sending a nude selfie by scanning the image and blocking it from leaving the device, for example.


Cilter empowers parents to protect their children by keeping them informed of imminent threats to their child. Alerts are sent to parents if Cilter detects grooming patterns, self-harm searches, bullying or harassment.

Fast Alerts

By identifying grooming patterns and sending alerts to parents, no other parental control goes to such forensic depths to protect children as Cilter!

Protecting Children Online

Good. Better. Best. Cilter

Risks posed to children online are very much the Zeitgeist and while parental controls currently focus on
monitoring and blocking offensive URL’s, there is no product that actively filters/blocks Communication via messaging apps and Social media sites. The World needs a solution to protect children from bullying, harassment and grooming. Cilter is that solution!
