Every time someone in your office opens a browser, visits a website, or clicks a link — a DNS lookup happens. It’s invisible, it’s instant, and in most businesses across the UAE, it’s completely unprotected.
That means your ISP — and anyone who can intercept that traffic — can see every domain your business visits. Every tool you research. Every competitor you look up. Every website your team browses throughout the working day.
Most businesses don’t know this is happening. The ones that do, often assume it’s too technical or too expensive to fix.
It isn’t. And this post explains exactly what you can do about it — and how Tech Abrahams can set it up for you.
What Is DNS — and Why Should You Care?
DNS stands for Domain Name System. Think of it as the phone book of the internet. When you type google.com into your browser, your device asks a DNS server: “What’s the IP address for google.com?” The DNS server replies, and your browser connects.
The problem? By default, that lookup is sent in plain text — unencrypted, unprotected, and fully visible to your ISP and anyone monitoring your network.
This means:
- Your internet provider can log and analyse every domain your business visits
- Malicious actors on your network can intercept or manipulate DNS responses
- Employees can accidentally reach phishing sites, malware domains, or inappropriate content with zero filtering in place
- Your business browsing behaviour is essentially an open book
For businesses in the UAE — where data privacy, corporate confidentiality, and regulatory compliance are increasingly important — this is a significant risk that most IT setups completely ignore.
The Fix: Secure, Private DNS
The solution is straightforward: replace your default ISP DNS with a secure, encrypted DNS resolver that filters malicious domains, protects your privacy, and gives you control over what your network can and cannot reach.
There are several excellent options depending on your needs.
Option 1: Quad9 — Security-First DNS
Quad9 (9.9.9.9) is a non-profit DNS resolver with one primary mission: block malicious domains before your device ever connects to them.
Every DNS query is checked against a real-time threat intelligence database maintained by IBM, Global Cyber Alliance, and other security organisations. If a domain is known to host malware, ransomware, phishing attacks, or other threats — Quad9 blocks it silently, before your device loads anything.
Why it matters for UAE businesses:
- Free to use, no account required
- Blocks known malicious domains automatically — no configuration needed
- Supports DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) — meaning queries are encrypted and private
- No logging of personal data — your browsing isn’t being sold or analysed
- Backed by a non-profit structure with no commercial incentive to monetise your data
Quad9 is a strong baseline for any business that wants basic threat protection without complexity.
Option 2: Cloudflare DNS — Speed and Privacy
Cloudflare’s 1.1.1.1 is consistently ranked as the world’s fastest DNS resolver. For businesses where responsiveness matters, Cloudflare delivers DNS queries in milliseconds with a strong commitment to privacy.
Cloudflare offers:
- 1.1.1.1 — Fast, private DNS with no query logging
- 1.1.1.2 — DNS with malware blocking enabled
- 1.1.1.3 — DNS with malware and adult content filtering
All variants support encrypted DNS protocols (DoH and DoT), ensuring that your queries are never visible in plain text.
Why it matters for UAE businesses:
- Cloudflare has edge nodes in the region, meaning low-latency resolution
- Encrypted by default when configured correctly
- 1.1.1.2 and 1.1.1.3 variants give you filtering without requiring additional infrastructure
- Trusted by enterprises globally for reliability and uptime
Option 3: NextDNS — Full Control, Full Visibility
If Quad9 and Cloudflare are the “set it and forget it” options, NextDNS is for businesses that want to see everything and control everything.
NextDNS is a cloud-based DNS resolver with a dashboard that gives you:
- Real-time logs of every DNS query across your network
- Customisable blocklists — block ads, trackers, malware, adult content, social media, or any domain category you choose
- Per-device or per-user filtering profiles
- Analytics showing which domains are being queried most frequently
- Encrypted DNS (DoH and DoT) across all queries
- The ability to whitelist specific services your business needs
Why it matters for UAE businesses:
- Complete visibility into what your network is actually doing — invaluable for IT audits and compliance
- Block entire categories of sites (gambling, social media, streaming) during work hours
- Identify if a device on your network is communicating with suspicious infrastructure
- Free tier available; paid plans start from a few dollars per month for unlimited queries
For businesses that want DNS to also function as a lightweight network monitoring and policy enforcement tool, NextDNS is exceptional value.
Option 4: Pi-hole + AdGuard Home on a Dedicated Device — The On-Premise Solution
For businesses that want maximum privacy and zero reliance on third-party cloud DNS providers, Pi-hole and AdGuard Home offer on-premise DNS filtering that runs entirely on your own hardware.
This is where Tech Abrahams specialises — and where most IT providers in the UAE simply don’t go.
What Is Pi-hole?
Pi-hole is an open-source DNS sinkhole. It acts as a DNS server for your entire network, filtering out ads, trackers, and malicious domains at the network level — before they ever reach any device. Every computer, phone, printer, and smart device on your network benefits automatically, with no software installed on any endpoint.
What Is AdGuard Home?
AdGuard Home is a more feature-rich alternative to Pi-hole that combines DNS filtering with encrypted DNS upstream, a built-in DHCP server, per-client settings, and a clean, modern web interface. It’s arguably easier to manage for non-technical administrators.
The Dedicated Portable Device Approach
Tech Abrahams deploys Pi-hole or AdGuard Home on a dedicated, compact device — purpose-built, pre-configured, and ready to plug into your network. Think of it as a small, silent box that sits next to your router and takes care of DNS for your entire office.
Why this matters for UAE SMBs:
- Your DNS queries never leave your building — completely private, no third-party cloud involved
- No subscription fees — you own the hardware and the software
- Works for every device on your network without any per-device configuration
- Block thousands of ad and tracking domains by default — reducing bandwidth consumption and speeding up browsing
- Encrypted upstream DNS (to Quad9, Cloudflare, or NextDNS) can still be configured for the outbound query
- Easy to take between office locations — plug in, and it works
- Full query logs stored locally — visible to you, not to any vendor
For a business that handles sensitive client data, operates in a regulated industry, or simply wants complete control over their network traffic, this is the gold standard.
Why UAE Businesses Specifically Should Take DNS Seriously
In the UAE, internet traffic is subject to oversight by telecommunications regulators. Your ISP’s DNS resolver — the one every device uses by default — is a straightforward way for third parties to observe which domains your business visits.
This doesn’t mean anything illegal is happening. But it does mean:
- Your competitive research, vendor negotiations, and business browsing are visible
- Employee browsing behaviour is not private
- There is no filtering layer stopping staff from accidentally visiting phishing or malware sites
- Your business has no visibility into what its own network is doing
Switching to encrypted, private DNS — whether cloud-based like Quad9, Cloudflare, or NextDNS, or fully on-premise like Pi-hole or AdGuard Home — addresses all of these issues at once.
What Tech Abrahams Does for You
DNS security sounds technical. The implementation, if done properly, isn’t something you should be configuring yourself — especially if you want it to work correctly across every device, with proper logging, encryption, and failover.
Here’s what Tech Abrahams handles:
Assessment — We review your current DNS setup, identify what’s exposed, and recommend the right solution for your business size and budget.
Deployment — Whether it’s configuring encrypted DNS on your router, setting up NextDNS with a custom filtering profile, or deploying a Pi-hole or AdGuard Home device on-premise, we handle the full implementation.
Configuration — We tune the filtering rules, set up logging, configure encrypted upstream DNS, and ensure every device on your network routes through the secure resolver.
Training — We show your administrator how to read the dashboard, whitelist or block domains, and understand what the logs are telling you.
Ongoing Support — Blocklists need updating. New threats emerge. Devices get added. We stay in the background so your DNS layer keeps working correctly.
Which Solution Is Right for Your Business?
| Quad9 | Cloudflare | NextDNS | Pi-hole / AdGuard | |
|---|---|---|---|---|
| Threat blocking | Yes | Yes (1.1.1.2) | Yes | Yes |
| Encrypted DNS | Yes | Yes | Yes | Configurable |
| Dashboard/logs | No | No | Yes | Yes |
| On-premise | No | No | No | Yes |
| Cloud dependency | Yes | Yes | Yes | No |
| Custom filtering | No | Limited | Full | Full |
| Best for | Simple protection | Speed + privacy | Visibility + control | Maximum privacy |
Tech Abrahams can deploy any of these — or a combination. Many clients run an on-premise AdGuard Home device with encrypted upstream queries going to Quad9 or Cloudflare, giving them local control and cloud-level threat intelligence at the same time.
The Bottom Line
Your ISP’s default DNS is not private, not filtered, and not protecting your business. Switching to a secure DNS resolver is one of the most cost-effective cybersecurity improvements any UAE SMB can make — and it protects every device on your network at once.
The technology is proven. The setup is straightforward for a specialist. The ongoing cost is minimal to zero.
The only thing stopping most businesses is not knowing it’s possible.
Now you do.
