Most cyberattacks start with a malicious link, a spoofed domain, or a compromised website. DNS and web filtering stops them at the source — before a user even makes a connection — protecting your business around the clock, on every device, everywhere.
Every time someone on your network clicks a link or types a web address, a DNS lookup happens. That lookup is your earliest opportunity to stop a threat — before any malicious content ever loads.
A device on your network — or a remote worker's laptop — attempts to reach a web address. This triggers a DNS query to look up where that address lives.
Instead of going straight to a public DNS server, the query routes through our filtering layer, which checks the destination against a continuously updated threat intelligence database.
Known malicious domains, phishing pages, ransomware delivery sites, and prohibited categories are blocked instantly. Safe destinations are resolved and the connection proceeds normally.
If blocked, the user sees a clean notification explaining the site is restricted. If allowed, the page loads as expected — the filter is completely invisible during normal browsing.
Traditional security tools — antivirus, firewalls — react to threats that have already reached your device. DNS filtering operates upstream, intercepting threats before any data is transferred. It’s the difference between locking the front door versus chasing an intruder through your office.
DNS and web filtering intercepts a broad range of threats that bypass traditional defenses — often before your security tools even know they exist.
Phishing emails typically drive victims to fake login pages designed to harvest credentials. DNS filtering blocks those destination domains the moment they're classified as malicious — even brand-new ones.
Ransomware is frequently delivered through drive-by downloads from compromised or malicious websites. Blocking the domain stops the payload before it ever reaches a device.
After malware infects a device, it tries to "phone home" to a command server for instructions. DNS filtering cuts that communication channel, neutering the malware even after infection.
Attackers register domains like "arnazon.com" or "m1crosoft.com" to catch users who mistype URLs. Threat intelligence flags these automatically, protecting against honest mistakes.
Sophisticated attackers tunnel stolen data out through DNS queries — a method that bypasses many traditional security tools. DNS filtering with analytics detects these unusual traffic patterns.
Block access to categories like gambling, adult content, or peer-to-peer file sharing — reducing legal liability, bandwidth waste, and exposure to malware-laden sites in those categories.
We deploy, configure, and manage DNS filtering as part of your layered cyber security stack — not as a standalone product you have to figure out yourself.
We handle setup across your entire network — routers, access points, and individual devices — ensuring every DNS query is protected from day one.
A lightweight roaming client extends filtering to laptops and devices regardless of where they connect — home networks, hotel Wi-Fi, coffee shops, or airports.
Our filtering platform draws from continuously updated threat intelligence feeds, catching newly registered malicious domains — often within minutes of classification.
We provide regular reports showing what's being blocked, how many threats were intercepted, and which devices or users are generating the most risk-related traffic.
Not every business has the same browsing requirements. We configure filtering policies that match your work environment — blocking what should be blocked without disrupting legitimate work.
DNS filtering works alongside your firewall, endpoint detection, and email security as a coordinated layer — not an isolated product.
See what you actually get with managed network security versus a basic firewall-and-forget approach or trying to manage it yourself.
| CAPABILITY | Managed DNS & Web Filtering | Antivirus / EDR Only | Firewall Only |
|---|---|---|---|
| Next-Gen Firewall | ✓ DNS-level, pre-connection | ✗ Reacts after download | ✗ Port/IP level only |
| Protects remote workers | ✓ Roaming client | ✓ On device | ✗ Office perimeter only |
| Blocks new/unknown malicious domains | ✓ AI Threat intel feeds | ✗ Needs known signature | ✗ Port/IP rules only |
| Command & control blocking | ✓ VLANs designed & managed | ✗ Behavioral detection | ✗ Limited visibility |
| Content & category policy | ✓ IDS/IPS active | ✗ | ✗ |
| Web traffic reporting & logging | ✓ RMM + managed EDR | ✗ | ✗ Firewall logs only |
| Compliance documentation support | ✓ VPN + MFA enforced | ✓ Endpoint Activity | ✗ Limited |
The most effective security posture uses all three layers in combination. DNS filtering covers the web layer upstream. Endpoint detection covers the device layer. Firewall management covers the network perimeter. Megabyte IT deploys and manages all three as a coordinated stack — not separate disconnected tools.
No. DNS filtering operates in milliseconds — typically under 2ms — because it only checks the domain name before a connection is made, not the actual web content. Normal browsing feels exactly the same. The only time users notice the filter is when they try to reach a blocked site, in which case they'll see a brief, clear explanation that the site is restricted.
Yes — and here's why. Antivirus and EDR react to threats that have already reached a device. Your firewall filters by IP address and port, not by domain name or content. DNS filtering fills the gap between them, blocking threats at the domain lookup level before any malicious content is downloaded. Each layer catches what the others miss. A business relying on only one or two of these layers has significant blind spots.
Yes — small businesses are the primary target for most automated cyberattacks specifically because they tend to have weaker defen
False positives can happen, though they're uncommon with well-maintained threat intelligence. When they do, we handle it quickly — a quick call or ticket gets a legitimate site added to the allow list, usually within minutes. We also perform regular policy reviews to catch any persistent issues before they become problems. You're not left on your own to sort it out.
ses than larger enterprises. Ransomware operators, in particular, frequently target law firms, CPA practices, medical offices, and oil and gas companies — all common in Acadiana — because they hold valuable data and often pay ransoms to get operations back up quickly. Being small doesn't make you invisible. It makes you a preferred target.
Yes. A lightweight roaming client deployed on managed devices ensures DNS filtering applies everywhere the device goes — home networks, travel, client sites — not just when connected to your office network. This is critical for businesses with remote or hybrid workforces, since most attacks targeting employees happen outside the office perimeter.
Yes. Filtering policies can be applied by user group, device, or network segment. For example, you might allow social media access for your marketing team while blocking it for back-office staff, or permit certain cloud storage tools for specific users while restricting them broadly. We configure these policies based on your operational requirements.
Many insurers are now asking specifically about web filtering controls as part of the underwriting questionnaire. Having managed DNS filtering in place — with logging — directly supports those requirements and demonstrates a proactive security posture. Businesses that can document layered security controls often qualify for better rates and higher coverage limits than those without.
For most small businesses, network-wide DNS filtering can be operational within a single visit or remote session. Roaming client deployment to endpoints is handled through our remote management platform and typically takes a few hours across a full device fleet. You'll have meaningful protection in place the same day we start.
