Firewalls and network security appliances
We build and deploy dedicated security devices — including our own Raspberry Pi based dual-band WiFi security appliance — that sit between your network and the internet and block what should not get in.

Cyber Security Advisory, Firewalls & Network Protection for Companies
Small and mid-size companies are attacked more often than large ones because attackers assume nobody is watching. We install the watching. Our security work ranges from a purpose-built WiFi security appliance for an office, to network traffic monitoring during a live intrusion investigation, to a full audit of what an outsider can reach. All engagements are strictly confidential.

What we build
DDoS and DoS protection
Rate limiting, upstream filtering and edge protection (Cloudflare and equivalents) so a flood of traffic does not take your website, portal or API offline.
Intrusion detection and traffic monitoring
Ethernet and WiFi traffic capture with detection rules that flag unknown devices, beaconing malware, data exfiltration and backdoor call-homes in real time.
Backdoor and incident investigation
If you suspect a compromise — an ex-employee, a vendor, a strange device on the network — we investigate quietly, find the entry point and close it, with a written report.
Penetration testing and security audits
We test your website, portal, WiFi and office network the way an attacker would, then give you a prioritised fix list in plain language.
Device forensics
Android and iOS device scanning and office LAN scanning for spyware, unauthorised apps and data leakage.
Attacks we protect you against
- DDoS / DoS traffic floods
- Brute-force login attacks
- Phishing and credential theft
- Ransomware and malware
- Man-in-the-middle on WiFi
- Rogue devices and evil-twin access points
- SQL injection and web app attacks
- Backdoors and remote-access trojans
- Data exfiltration by insiders
- Unpatched services exposed to the internet
How an engagement runs
Confidential assessment
An NDA first if you want one. Then a review of your network, devices and public exposure — usually one on-site visit in Chennai.
Risk report
What an attacker can reach today, ranked by damage and ease. No jargon.
Fix and harden
Appliances installed, firewalls configured, services patched, monitoring switched on.
Monitor and retest
Ongoing alerts to your phone and a retest after changes, so the protection stays real.
Questions businesses ask us
Is the engagement confidential?
Completely. We sign an NDA on request, we never name clients, and findings are shared only with the people you authorise. This page deliberately lists no client names.
We are a small company. Do we really need this?
Attackers automate; they do not check your size. A single ransomware event costs more than a year of protection. Start with the assessment and decide from the report.
Can you stop DDoS attacks?
For websites, portals and APIs, yes — with edge filtering and rate limits, most floods are absorbed before they reach your server. For office links we add local rate limiting and upstream ISP coordination.
What is a WiFi security appliance?
A dedicated device we build that replaces or sits behind your office router, isolating guest traffic, blocking unknown devices and logging everything. One is deployed with a client in Chennai and has been running without incident.
Do you do penetration testing legally?
Only with written authorisation from the system owner, with agreed scope and timing. We will not test anything you do not own.
Free consultation
Tell us the problem. We'll tell you if it needs AI, a device, or neither.
Thirty minutes on the phone or at our Anna Nagar West office. You leave with a clear recommendation and, if it makes sense, a fixed quote. No obligation.
Every client engagement is confidential. We do not publish client names, project details, screenshots or testimonials without written permission, and we sign an NDA before any assessment on request.
