A deal can take months to build. A single compromised conversation can put it at risk.

Confidential discussions deserve more than a closed door.

With SMG — Secure Meeting Guard, organizations can take a stronger approach to protecting sensitive conversations from unauthorized listening risks.

Secure the room. Protect the conversation.

Would your meeting room pass a security check?

Even walls have ears.

And sometimes, the threat may be hiding in plain sight.

An everyday object can conceal a SIM-based device.

Is your secure room really secure?

A life-term convict. A maximum-security prison. A working mobile phone.

NDTV, 12 August 2026: former MP Prajwal Revanna, serving a life sentence, was allegedly found using a mobile phone inside Bengaluru prison during a surprise Crime Branch raid. A case has been registered. Officials are still trying to establish how the handset got in.

That last line is the whole problem.

Every prison in the country already has rules against mobile phones. Most have search protocols. Many have some form of signal denial installed. And handsets keep turning up - in cells, in raids, in viral videos.

Because partial coverage is not enforcement.

A system that blankets one block and leaves the next uncovered. A deployment tuned for 2G-era bands while inmates run 4G and 5G. Signal denial that fails at the cell wall, the barrack corner, the high-value ward where it matters most. Contraband doesn't need a gap in the policy. It only needs a gap in the coverage.

Prison signal-denial capability in India needs to move from installed to enforced - full-band, verified block-by-block, measured against real handsets in real cells, and audited after commissioning rather than at it.

Until then, every raid will end the same way: a phone on the table, and a question nobody can answer.

ANI, 08 August 2026: an IAF Wing Commander arrested for allegedly leaking defence information after being honey-trapped through social media by Pakistani intelligence operatives.

No breach of a perimeter. No forced entry. No stolen documents.

Just a handset - and a stranger who was patient.

A mobile phone is a microphone, a camera, a location beacon and a transmitter. It sits in a pocket through every briefing. It travels into every restricted area it isn't stopped from entering. It remembers everything it touches.

Hostile services no longer need to get inside your facility. They need to get inside one person's phone.

The threat is in the pocket.

A pan-India drug network. Run from inside a jail cell. Coordinated over WhatsApp, settled over UPI.

In Goa, investigators say a convicted NDPS accused operated a nationwide narcotics racket from inside Colvale Central Jail - no physical contact, just a phone. Suppliers, dealers, collection points, payments: all run over WhatsApp calls and messages from behind bars.

The prison walls did their job. The smuggled phone didn't care.

Authorities are now evaluating jammers to shut such signals down. But blanket blocking has a blind spot - it can deny a call, yet it never tells staff which cell the phone is in, or lets them recover it.

The Prison Communication Guard (PCG) is built differently. It detects active mobile device activity inside the facility and pinpoints the device's exact location - so staff don't just suppress the signal, they find the handset and dismantle the operation at its source.

Detect. Locate. Intervene.

A remanded prisoner at HMP Exeter. A mobile phone in hand during a cell search. A SIM card and a USB device found weeks later.

This isn't rare. It's routine.

Contraband phones turn a locked cell into an open line - used to run rackets, intimidate witnesses, and coordinate crime from inside secure walls. The bars hold the person. They do nothing to hold the signal.

That's the gap the Prison Communication Guard (PCG) closes. The moment a smuggled phone powers up and connects, PCG detects the active device and pinpoints where it is inside the facility - turning a hidden handset into an actionable location for staff to act on.

In Iloilo, surprise "greyhound" operations recovered eight smartphones, five keypad phones, and improvised weapons from inside two facilities - and officials confirmed the sweeps will now repeat at least once a month. Every one of those phones was live inside a cell before it was ever found.

Manual sweeps are periodic. Illicit phone use isn't.

SHYAM VNL's PCG detects active cellular activity inside the facility - flagging phones in use within the barracks continuously, not once a month. It turns contraband control from a scheduled search into a permanent watch, so a live phone is spotted the moment it's active, not weeks later.

Four phones. One high-security jail. And the same question the police always end up asking - how did they get in?

At Faridkot Central Jail, a routine search recovered four mobile phones from inmates, including a gangster allegedly linked to the Arsh Dalla network. By then, the phones were already inside. The barracks were already compromised.
