Delhi has gone into fortress mode. With the 18th BRICS Summit looming, the capital has activated what officials describe as a multi-layer security blanket: layered barricades, counter-drone systems, AI-assisted surveillance grids, and thousands of personnel fanned across the city's arterial roads. For a city that has already hosted the G20 in 2023 and the Pravasi Bharatiya Divas, this is familiar choreography, but the BRICS footprint is bigger, messier, and far more geopolitically charged, and that changes what "security" has to mean this time.
What Is the 18th BRICS Summit and Why Delhi Is Hosting It
BRICS began in 2009 as a four-nation acronym, Brazil, Russia, India and China, and later added South Africa. Since 2024, it has expanded to include Egypt, Ethiopia, Iran, the UAE and Indonesia, giving the bloc a combined population of roughly 40% of humanity and around a third of global GDP in purchasing-power terms.
India took over the BRICS chairmanship from Brazil, which hosted the 17th Summit in Rio de Janeiro in July 2025, and Russia before that in Kazan in October 2024. New Delhi last hosted the bloc in 2012, and again in Goa in 2016. The 2026 edition is widely expected to be anchored at Bharat Mandapam in Pragati Maidan, the same complex that carried the G20 Leaders' Summit.

Why does that matter for the average Delhiite? Because a leaders-level summit means road closures, metro route changes, airspace restrictions and hotel bookings vanished overnight. The G20 precedent saw Delhi Police advise large parts of the city to work from home for three days.
The Core News: What the Multi-Layer Security Blanket Actually Looks Like
Security planners describe the arrangement as concentric rings, where each layer assumes the previous one has failed. Here is the rough architecture, based on how Delhi has handled comparable mega-events.
- Outer ring (city-wide): Randomised vehicle checks, heightened patrolling, and anti-sabotage sweeps across markets, bus terminals and railway stations.
- Middle ring (approach corridors): Multi-layered barricades with static pickets on key radial roads, plus armed response teams parked at chokepoints.
- Inner ring (venue and hotels): Sanitised zones around Bharat Mandapam and the five-star properties on the Sardar Patel Marg and Chanakyapuri belt where delegations typically stay.
- Air layer: A hardened no-drone envelope over central Delhi, with RF jammers, radars and counter-UAS teams positioned on rooftops.
- Cyber layer: Monitoring of the summit's digital attack surface, from spoofed Wi-Fi access points to social media disinformation.
Delhi Police operates with a sanctioned strength of more than 97,000 personnel, and summit duty means drawing from that pool while borrowing paramilitary companies from the CISF, ITBP and CRPF. The NSG, whose four regional hubs cover the capital, stays on standby for counter-terror and hostage scenarios, while the SPG handles the Prime Minister's proximate protection.
The G20 template is the working blueprint
At the G20 Summit in September 2023, Delhi deployed upwards of a lakh police and security personnel, shut arterial corridors around Pragati Maidan, and coordinated 40-plus heads of state and dozens of bilateral meetings over a single weekend. BRICS brings a similar logistics load with a different political texture, since the guest list includes leaders under Western sanctions and countries with active rivalries.
Why This Matters: The Stakes Beyond Protocol
A summit security failure is not just a policing problem. It is a sovereignty signal. India is using the chairmanship to pitch itself as the natural convenor of the Global South, and every visible crack in the security perimeter becomes a story in capitals that are deciding whether to back New Delhi's vision of a reformed multilateral order.
Three things are genuinely at stake:
- Diplomatic credibility. Hosting a bloc with Iran and Israel-aligned powers in the same room requires airtight arrangements around bilaterals that may never be publicly announced.
- Economic signalling. BRICS is pushing local-currency trade settlement and a shared payment rails conversation, and the summit is where those announcements get made.
- Domestic politics. Delhi's security apparatus is under constant scrutiny, and a high-profile breach would hand ammunition to critics at every level.
| Dimension | G20 Delhi (2023) | BRICS Summit (Delhi) |
|---|---|---|
| Venue | Bharat Mandapam, Pragati Maidan | Same complex, reported |
| Delegation profile | 40+ heads of state and government | BRICS members plus invited partners |
| Airspace regime | No-drone red zone, IAF coordination | Expected to be at least as strict |
| Workforce impact | Work-from-home advisory citywide | Likely similar, with school and office advisories |
Key Details: The Tech Stack Behind the Shield
Facial recognition and video analytics
Delhi's Safe City Project has pushed the city's CCTV footprint toward six figures, with tens of thousands of cameras already networked into command centres. Under summit conditions, that footage gets fed into AI-powered video analytics: face matching against watchlists, abandoned-object detection, and crowd-density estimation that flags abnormal movement before it becomes a crush.
Counter-drone systems
Small commercial quadcopters remain the single biggest soft spot in any open-air VIP event. The standard playbook combines RF detection, radar and acoustic sensors, and effectors such as jammers or net-capture guns. Delhi already sits inside a permanent DGCA red zone where drone operations require explicit clearance, so the summit simply tightens an existing framework rather than inventing one.

AI-assisted traffic management
Delhi has been rolling out adaptive traffic signal systems that use cameras and machine learning to retime signals based on real-time queue lengths. During a summit, the same tech is used in reverse: engineers build green corridors for motorcades and then rebalance the network so the rest of the city does not gridlock entirely.
The numbered playbook planners actually follow
- Threat assessment with intelligence agencies, producing a graded risk matrix for each venue.
- Zone declaration that formalises restricted areas and the legal powers attached to them.
- Physical sanitisation of venues, hotels, and the routes between them, days in advance.
- Tech overlay, meaning cameras, sensors, jammers and command-centre integration.
- Dry runs and VIP rehearsals, including mock motorcades and emergency drills.
- Live monitoring from a central control room that can push instructions directly to field units.
Competitive Landscape: How Other Capitals Handle Mega-Summits
Delhi is not unique in this. Every BRICS host has faced the same problem, and each solution reveals something about the city.
- Kazan 2024 leaned on Russia's heavy domestic security apparatus and lockdown-style restrictions, with drone attacks on the region underlining why air defence at summits is no longer theoretical.
- Rio de Janeiro 2025 deployed thousands of troops and police in a city where security forces and organised crime routinely collide, making the perimeter problem far harder.
- Johannesburg 2023 and New Delhi 2023 both leaned on layered static pickets plus highway closures, a model Indian planners know well.

The competitive subtext: India wants to prove it can run a smooth, tech-forward, disruption-light summit, unlike the lockdown-heavy Russian model. That softer approach is exactly why AI and analytics vendors are watching closely.

What This Means for AI-Tool and AI-News Publishers
This story is unusually rich for anyone running an AI newsletter, tool-review site, or tech blog from India. Five concrete angles:
- "The summit tech stack" explainer. Break down facial recognition, counter-drone RF systems, and adaptive traffic signals as separate mini-posts, each targeting high-intent searches like "AI traffic management India" or "anti-drone systems India."
- Vendor watchlist. Government tenders for surveillance and analytics are public. Build a running list of Indian AI surveillance vendors and pitch it as a tracker readers can bookmark.
- Privacy angle. Facial recognition at mass events is a guaranteed debate magnet. A balanced piece on legality, accuracy and false positives in Indian deployment will attract links from law and policy blogs.
- SEO timing play. Traffic around any big summit spikes in a narrow two-week window. Pre-write the explainer, the "road closures" utility post, and the tech deep-dive now, then publish as search demand climbs.
- Global-comparison content. "How Delhi's summit security compares with Rio and Kazan" is the kind of comparative piece that travels well across English-language audiences.
Challenges Ahead: What Could Go Wrong
- Drone incursions remain the hardest problem. Detection is easier than mitigation, especially in dense urban airspace with legitimate helicopter and aviation traffic overhead.
- Facial recognition accuracy is contested. False matches at scale can create wrongful detentions and a reputational crisis mid-summit.
- Traffic pain is basically unavoidable. No amount of adaptive signalling fully absorbs the closure of central Delhi's arterial roads.
- Guest-list friction. Sanctioned leaders and rival delegations mean bilateral scheduling can shift at short notice, forcing security re-plans in real time.
- Cost and fatigue. Multi-day deployments strain the same police force that manages protests, festivals and VIP movement year-round.
- Information vacuum. Restricted-zone rules are often communicated late, leaving residents and businesses scrambling, which is itself a governance risk.
Final Thoughts
Delhi's multi-layer security blanket is less about any single technology and more about coordination at speed, which is exactly where the AI layer now earns its place. The real test is whether the city can project calm competence while letting 20 million residents keep functioning. If this summit goes smoothly, the bigger story will not be the barricades, but the surveillance and analytics infrastructure that quietly stays behind after the delegations fly home.
FAQ
What is the 18th BRICS Summit?
It is the leaders-level meeting of the expanded BRICS bloc, which now includes Brazil, Russia, India, China, South Africa, Egypt, Ethiopia, Iran, the UAE and Indonesia. India is chairing and hosting, with New Delhi expected as the summit city and Bharat Mandapam as the likely venue.
Why has Delhi been put under high alert?
Heads of state from a bloc that includes countries with active rivalries and sanction exposure create an elevated threat profile. Delhi responds with layered barricades, counter-drone systems, AI-assisted CCTV analytics and thousands of extra personnel.
Who is affected by the security arrangements?
Central Delhi commuters, businesses around Pragati Maidan and Chanakyapuri, metro riders, and hotel and airline staff face the sharpest disruption. Past mega-summits have triggered citywide work-from-home advisories and school closures.
When can residents expect restrictions to begin?
Typically sanitisation and barricading start several days before leaders arrive, with the strictest airspace and road restrictions clustering around the leaders' session itself. Advisory notices usually get published one to two weeks ahead.
What are the biggest risks or concerns?
Drone incursions, facial recognition false positives, lingering traffic paralysis and late communication of restricted-zone rules top the list. Privacy advocates also argue the surveillance build-up outlasts the event itself.
Will any of this technology remain after the summit?
Almost certainly. CCTV networks, analytics platforms and command-centre integrations installed for the event are permanent capital investments, which means the summit often marks a lasting upgrade to a city's surveillance baseline.
