Use case

Web filtering on every employee phone, with privacy built in

Phishing links, malware sites, and risky content reach employees’ phones through browsers, messaging apps, and search ads, and AI is making each lure harder to spot. Reflex, Corrata’s on-device threat engine, filters that content on the phone itself across every channel, in a way employees can’t easily bypass and without ever recording their browsing.

Messaging apps can deliver phishing links aimed directly at your organisation, well outside the reach of email security.

Employees browsing the web can click on content that looks harmless, particularly on risky sites known for hosting malware.

How Reflex filters web content on the device

Reflex inspects network traffic on the phone itself, across all ports and every key protocol, reading details such as domain and server names, IP addresses, and SSL certificate metadata. Because it sees more than DNS traffic, its filtering can’t easily be bypassed. Because it runs on the device, it can apply privacy protections and policies tailored to your organisation and to individual employees.

Addressing the danger of risky content

Malicious links

Filter malicious links from every channel.

Malicious links can be embedded in web pages, included in search ads, or delivered by SMS, email, WhatsApp, or any of the collaboration tools employees use every day. Reflex filters malicious content across the whole device, however it arrives, which is the same protection that blocks the sites behind mobile phishing lures.

Acceptable use

Make it easy for employees to follow acceptable use guidelines.

Many organisations block illegal, adult, gambling, or other categories of content to meet their acceptable use guidelines. Even if that isn’t a concern for your business, these sites are notorious for hosting malicious content.

Controls which are difficult to circumvent

Corrata’s network traffic inspection stops content controls being routinely bypassed.

Reflex applies filtering even when a browser or device uses encrypted DNS, and it covers traffic that goes straight to an IP address. Personal VPNs can also be restricted using Corrata’s usage controls, and our page on on-device network traffic inspection explains how this works.

Privacy

Block risky content without recording browsing data.

Employee buy-in matters for any security product, and especially on phones, which are rarely used only for work. Corrata filters web content on the device, and nowhere in the Corrata system is a record kept of individual attempts to reach non-compliant sites, an approach we call privacy by architecture.

Mobile web filtering FAQs

Why does mobile web filtering matter?

Most organisations filter the content employees reach on desktops and laptops, because it removes a wide range of risky content such as phishing, malware, and NSFW sites. Phones carry the same business apps and data, so without mobile web filtering, that control is missing on the device employees use most.

How does Corrata keep web filtering private?

Corrata filters web content on the device and works anonymously by default, so benign browsing is never recorded. An individual employee only becomes identifiable when a security-critical incident takes place, which is part of an approach we call privacy by architecture.

How does Reflex outperform DNS-based web filtering?

DNS-based filtering only sees unencrypted DNS lookups. Reflex inspects all IP traffic on the device, so it can filter content reached using encrypted DNS and traffic that goes straight to an IP address. Our page on on-device network traffic inspection explains how this works.

Can employees bypass mobile web filtering with a VPN or encrypted DNS?

Not easily. Reflex applies filtering even when a browser or device uses encrypted DNS, and Corrata’s usage controls can restrict personal VPNs, so content controls aren’t routinely circumvented.

Which categories of content can Corrata block?

Corrata can block a wide range of content categories, from phishing and malware sites to gambling, adult, and illegal content. Policies can be set for the whole organisation or tailored to individual employees.
